World of Technicolor Hair

Blue, purple, green, no hair dye required. (Then again, they are mermaids.)

A setting where hair colors that would be unnatural in our world, such as blue, green, or purple, are the norm. People are just born with these hair colors or coloring your hair is just ubiquitous, and nobody bats an eye. This can sometimes be hand-waved with supernatural elements (eg. maybe it's set in an alien society), but other times the world is intended to be very similar to our own, except the characters have hair all over the rainbow for some reason.

One benefit of this is to distinguish characters from one another, especially in works with Only Six Faces. If the work is Speculative Fiction and the world in question is not meant to be similar to ours, giving everyone unnatural hair colors also heightens this fantasy. See People of Hair Color.

World of Technicolor Hair appears frequently, though not universally, in Japanese media as a common form of Anime Hair. It arose in manga that gave characters (who would have monochromatic hair in the actual printed pages) colored hair in the cover or side art. The intent may be Mukokuseki, or to make them look less definitively Japanese. For more information, see Hair Color in Japanese Media. As a result of the commonality of unusual hair colors in Japanese media, some specific colors have formed their own associations, such as Rose-Haired Sweetie and Shy Blue-Haired Girl.

For when the leads have hair all over the rainbow but the background characters don't, see Flashy Protagonists, Bland Extras.

Compare Amazing Technicolor Population, with which it might go hand in hand. See also Implausible Hair Color and Hollywood Genetics, where someone's hair is within the realm of human genetic possibility, but is unlikely for someone of their background, and Hair Color Dissonance, when unnaturally-colored hair is meant to stand in for another color (eg. purple hair being stylized black).

Examples:

Anime & Manga

• Assassination Classroom: The class includes students (all Japanese) with hair colors ranging from normal black and brown, to unusual but still realistic blonde and orange (Rio and Hinano), to blue (Nagisa), green (Kaede),^note Subverted when it's revealed that's she's naturally brunette and dyes her hair and bright red (Karma).
• B: The Beginning: Various characters have hair ranging from teal to lavender and pink, and it's never pointed out or questioned.
• BanG Dream!: It would be easier to list the hair colors that don't appear on the various girls of BanG Dream! But a sampling: Ako: purple, twins Sayo and Hina: mint green, Yukina: silver, Aya: hot pink, Kaouru: purple, Kanon: blue, Eve: white, Ran: black w/red stripe, Himari: pink, Moca: white.
• Beelzebub: Most of the demons have brightly coloured hair, like pink, blue or green. Although it's justified because they're, well, demons, no one in the human world comments on it.
• Bleach runs the entire range from natural hair types, to implausible hair types to impossible hair types. The impossible hair types include:
  • Blue hair: Grimmjow, Mayuri
  • Green hair: Nel, Mashiro
  • Pink hair: Szayel, Yachiru, Hacchi
  • Purple hair: Yoruichi (in the manga, she has black hair.)
  • Red hair: Renji, Jinta
• Bocchi the Rock!: Of the main cast alone, Hitori has pink hair (as do her mother and sister), Ryo has blue hair and Kita has bright red hair. Several other characters also have odd hair colors that nobody ever comments on.
• Code Geass: The Japanese characters tend to have semi-realistic brown or black hair, while the Britannian characters (and characters of Britannian descent, like Kallen) have somewhat more outlandish hair colors and styles. For example, Euphemia's pink and Cornelia's purple show up in flashbacks to their childhood, indicating it's completely natural. Other characters with unnatural hair include C.C. (bright green), Anya (pink), Jeremiah (blue), Nina (dark green) and Lloyd (lavender).
• Death Parade takes place in a sort of limbo world where humans go to be judged before their deaths by human-looking "arbiters." While the actual humans all have normal hair and eye colors, the arbiters have more Distinctive Appearances and mostly have unnatural candy-colored hair and eyes.
• In Demon Slayer: Kimetsu no Yaiba, most civilians have black hair, but more important characters tend to have brightly colored hair whether they're humans or demons. Among the main characters, Tanjiro's brown hair sometimes borders on dark magenta in some lighting, and Inosuke's black hair has blue highlights. The Hashira have even more outrageous hair colors; Shinazugawa and Uzui somehow have white hair despite being young adults, Rengoku has blond hair with streaks of red (which his father and brother have as well), and Mitsuri has pink and green hair. The only characters whose hair colors are explicitly considered unusual are Zenitsu (whose blond hair is Mistaken for Dyed even though it actually changed color after he was miraculously struck by lightning) and Mitsuri (whose outlandish hair colors were the result of eating 170 sakura mochi a day for eight months, and a potential suitor even rejected her because of it).
• Justified in The Disastrous Life of Saiki K.. The incredibly powerful psychic Saiki was born with hot pink hair, and in order to make himself less conspicuous, he brainwashed the entire world into thinking that odd hair colors were normal. In the present, many of the supporting characters have unnatural hair colors. Kaido and Teruhashi have blue hair, Hairo and Mera have scarlet hair, Kuboyatsu and Toritsuka have purple hair, and so on.
• The Diclonius in Elfen Lied have hair in varying shades of pink (in the anime, at least; in the manga only Nyu does). Justified in that they are not entirely human. Also, their hair color, combined with the cat-ear-like horns on their head, single them out among crowds of humans. Quite unusual for a manga, all the regular humans actually have realistic hair colors, and only the Diclonii live up to this trope. Only stand-out among the regular humans is Yuka who has straw blond hair, but is Japanese. However, we never see her parents, so she might have some Caucasian blood running in her family.
• The magical world of Fairy Tail has every shade of technicolor hair under the sun. For example, protagonists Natsu, Porlyusica, and Sherry have varying shades pink hair, Erza has cherry-red hair (for which Jellal gave her her surname Scarlet), Jellal, Wendy, and Juvia have varying shades of blue hair, Mirajane and her family have white hair, Brandish has lime green hair, and so on.
• Food Wars!, despite having a predominantly Japanese and Japanese-descended cast, gives its protagonist bright red hair and supporting characters hair shades like blue, green, and pink.
• Free!: Haru, Makoto, and Sousuke have relatively realistic dark hair, but many of the other Japanese characters have technicolor hair. Rei has blue hair, the Matsuoka siblings have purplish-red hair, Nagisa has bright blond hair, and the Mikoshibas all have red hair.
• Frieren: Beyond Journey's End takes place in a fantasy world where unusual hair colors are never commented on. While Frieren's Mystical White Hair could be justified by the fact that she's an elf, the human characters aren't exempt from having unnatural hair colors either, such as Himmel's bright blue hair, Heiter's green hair, and Fern's purple hair.
• Fushigi Yuugi: Tamahome and Chichiri have blue hair of different shades (but the former's hair is often mistaken for green), while Nuriko, his deceased little sister Kourin, and Empress Houki have purple hair. Chiriko's hair is a cross between brown and pink and the Nyan-Nyans have bubblegum blue hair. Tokaki, Subaru, and Tenkou have silver hair (this holds true for the former two even in youth), and Renhou and Miiru have silver-purple hair. Soi's hair is a shade of maroon, while Nakago is the only one who has blonde hair in the book world, and this is actually significant. The human forms of all the Beast Deities have hair in the color by which they are identified.
• In GA: Geijutsuka Art Design Class, the cast discusses why so many Western Animation works go for an Amazing Technicolor Population while anime would rather have World of Technicolor Hair—and to break the Fourth Wall, the scene shows their hair colors in more vivid saturations than usual: Kisaragi is dark brown, Professor is black, Tomokane is green, Noda is pink, and Namiko is dirty yellow. By the way, Awara is reddish-brown, Mizubuchi is black, Uozomi is blueish black, and Homura is blond. Yoshikawa is blond and Mitsui is blue.
• Inazuma Eleven: Characters' hair have every colour under the sun, both normal and unusual. The latter raises no eyebrows. Examples include:
  • Kazemaru, Haruna, Kogure, Rika, Domon, Tsurugi, Aoi, Kariya, Hiura have blue/teal/cyan hair.
  • Someoka, Touko, Tsunami, Kirino, Midori, Sakura, Nosaka have pink hair.
  • Kabeyama, Aki, Midorikawa, Morimura, Norika have green hair.
  • Kageno, Fuyuka, Tobitaka, Amagi, Manabe, Goujin have purple hair.
• A few characters in Interviews with Monster Girls have unusual hair colors, such as Yuki having teal hair and the Invisible Girl having bright red hair. Himari is noted to dye her hair auburn, but aside from that nobody seems to think anyone's hair color is strange, likely because demi-humans are already becoming an accepted part of society.
• Characters in JoJo's Bizarre Adventure can be born with hair ranging from blue to green to pink with black dots, but what truly makes it stand out is the anime's tendency to suddenly shift color palettes, which means the characters have a habit of suddenly changing hair color from one scene to another.
• Kill la Kill, in keeping with its ridiculously over-the-top nature, has several hair colors that fall outside of the realm of reality, like the grey-blue-haired Mikisugi, pink-haired Nonon, tealish-haired Houka, lilac-haired Rei, green-haired Uzu, and possibly Ryuko and Tsumugu, who both have red stripes in their hair, though the latter of two's could conceivably be a dye-job but, in Ryuko's case, it's actually a strand of life fibers that sprang from her being half-fused with them shortly after birth. Then there's Ragyo Kiryuin, whose hair is not only rainbow colored, but also shines its own light in a way reminiscent of a neon sign.
• If you live in the world of Lady!! and have pink or purple hair, chances are that you're a horrible person:
  • Madeleine Waverly has pink hair and is a Wicked Stepmother to Lynn and Sarah. She hates the fact that they're George's biological children and is cruel to them at every turn, going as far as to tell Lynn, at 5 years old, that she should go back to Japan and everyone would be better off without her. When George breaks off his engagement to Madeleine, Madeleine's (also pink haired) daughter Mary is so enraged that she returns from Switzerland to join Lynn's school just so she can tarnish her reputation and prevent her from gaining the Lady's Crest.
  • Jeanne has purple hair and is an abusive mother to her daughter, Sophie. She tried to raise Sophie to be cruel and manipulative like her, but thankfully Sophie broke away from her influence thanks to Lynn and Leonard.
  • Vivian has purple hair. She's regarded as a very beautiful woman by many, and is often followed around by an adoring Girl Posse that view her as near-ethereal. She's also an Academic Alpha Bitch that rivals Lynn.
• Love Live!: While some characters in the franchise have hair colors that can be considered normal in real life (like black or various shades of brown and auburn), others have hair in improbable shades of red, blue and purple (or in Rina's case, pink). However, it's implied that characters with blue or purple hair are really black-haired and their hair colors are just stylized to make them stand out.
• Almost no one in Lucky Star has normal colored hair. It's lampshaded when Miyuki (who has pink hair) explains to Konata (blue), Tsukasa, and Kagami (both purple) why exposure to sunlight and seawater changes hair color. Most, if not all, characters with funky hair colors also have that as their eye color. As such, one may pretend that their hair is perceived in their world as being black/dark brown. This is completely ignored and lampshaded further in the dub, where Konata comments that Miyuki is like her mother "down to the last pink hair." Also in the dub, Misao (who actually has brown hair) calls Konata "Shorty McBlueHair" at one point when she asks if that's who wants to borrow the game Kagami is asking her to return.
• Many characters in Magic Knight Rayearth have hair in unusual colors, and no one comments on it. Not only is this present in the fantasy world of Cephiro, but Hikaru has bright red hair and Umi has blue hair despite both being from Earth.
• Marginal Prince features characters with every hair color one can imagine. For starters, the main character Joshua is green-haired and his friend Henri sports blue hair, while Sylvain's is bright pink. In fact, every character has a different, mostly really bright hair color, and with the exception of Mikhail and Ivy (who are both blonde, but not related) none is seen twice among the group of important characters.
• My Hero Academia: Hair can be anything from blue to purple to pink to any mix imaginable. This is justified by the prevalence of Quirks, which have greatly changed human physiology. Even Quirkless people can have technicolor hair, such as Izuku, whose hair is dark green. Ironically, one of the only characters known to dye their hair is the Fiery Redhead Kirishima.
• My-HiME:
  • Fumi has light pink hair. Mashiro is purple. Nagi is white. For redheads, Nao is crimson, Midori reddish brown, Mai orange, and Shiho a salmon color. Natsuki has cobalt blue. Haruka is honey-blonde. This is all treated as normal.
  • The follow-up series, My-Otome has Tomoe with green hair and Nina with dark blue, while some background characters sport silver and purple. Any characters returning from My-Hime keep their original color.
• Mysterious Joker: Characters sport some unusual hair colors, which are implied to be natural. Silvery-blue for Joker, pink for Momo, purple for Ginko and Spade has a mix of blue and yellow.
• Naruto's hair colors are all over the place, like Sakura's pink, Gaara's, Sasori's, Kushina's, and Karin's reds, Konan's blue, and Kakashi's grey. There are also a surprising number of blondes for a culturally Japanese village, like Naruto himself, Ino, Temari, and Tsunade.
• Within Class 3-A of Negima! Magister Negi Magi alone there are at least 15 different colors of hair, despite the show being set on Earth.
• Neon Genesis Evangelion: The majority of the characters have realistic hair colors, but there are notable exceptions. Ritsuko is a natural brunette who dyes her hair blonde to distinguish herself from her mother, while Asuka, being a German-Japanese, has golden-red hair. Rei and Kaworu have blue and grey hair, respectively, which denotes their true origins: Rei is a clone of Yui Ikari mixed with the DNA of the Second Angel, Lilith, while Kaworu is the 17th Angel, Tabris.
• One Piece: Unusual hair colors are extremely common throughout the series, such as green (Zoro, Fukurou, Monet), blue (Buggy, Vivi, Franky), purple (Cracker, Tama, Orochi), pink (Kumadori, Bonney, Shirahoshi), orange (Nami, Kaku, Sadi), and red (Shanks, Kid, Ichiji). Some characters even have hair that is naturally two different colors (Inazuma's is half-white, half-orange. Giolla's is half-orange, half-yellow. Moscato's is half-pink, half-blue).
• Characters with bright, unnatural technicolor hair populate Pokémon: The Series. For example, Jessie has bright red hair, James has bluish-lavender hair, Officer Jenny has blue-green hair, Nurse Joy has pink hair, and Paul has purple hair.
• The Pretty Cure franchise is full of technicolor hair. Those in Futari wa Pretty Cure and Futari wa Pretty Cure Splash★Star have more-or-less natural (or close to it) colors. But after Yes! Pretty Cure 5 the girls get widely colored hair, mostly in a wild case of color coordination. It's usually the girls who are Precures who get crazy hair colors, to single them out as special; normal characters tend to have normal colors. Also, the Precures' hair colors are fairly dull while in civilian form, only to brighten up or change color entirely when they transform. Thirdly, there often tends to be one member of the team with a normal hair colour among the more wild colours (ex. Itsuki, Alice, Yuko).
  • In HeartCatch Pretty Cure!, the main leads have raspberry-pink hair (Tsubomi, Mizuki, and Futaba), blue hair (Erika), light violet hair (Momoka and Sakura), and deep violet hair (Yuri).
  • Smile PreCure! gives its leads a rainbow of hair; magenta for Miyuki, blood red for Akane, yellow for Yayoi, green for Nao, and blue for Erika. All but Yayoi inherited their hair colours from their mothers.
  • In Doki Doki! PreCure, there's magenta for Mana, blue for Rikka, purple for Makoto, and bright yellow for Regina.
  • HappinessCharge Pretty Cure! has magenta for Megumi and Kaori, blue for Hime, purple for Iona, and gray for Maria.
  • Maho Girls Pretty Cure! has golden-orange for Mirai, orange for her mother Kyoko, as well as Kay, purple for Riko, Liz, and Lian, blue for Lilia and Jun, bright yellow for Emily, and pink for Kotoha.
  • KiraKira★Pretty Cure à la Mode has bright orange for Ichika and Satomi, blue for the Tategami family, purple for Yukari, blood red for Akira and Miku, and bright yellow for Ciel.
  • HuGtto! Pretty Cure has magenta for Hana, purple-pink for Kotori, reddish-pink for Sumire, blue for Saaya and Reina, golden-yellow for Homare, and pale-yellow for Hugtan.
  • Star★Twinkle Pretty Cure: For the humans, there's pink for Hikaru, bright yellow for Elena and Sakurako, and purple for Madoka, and for the aliens, there's teal for Lala and blue for Yuni.
  • Tropical-Rouge! Pretty Cure has bright orange for Manatsu and Aoi, purple for Sango and Miyuki, blood red for Asuka, and royal blue for Yuriko.
• Puella Magi Madoka Magica features characters with pink (Madoka), blue (Sayaka), green (Hitomi), bright yellow (Mami), and red (Kyouko) hair, as well as a character with grey hair at a young age (Kyousuke, bonus points for his parents having normal (dark brown) hair). Curtains Matching the Windows is the norm and characters that are magical girls usually have the same color for their outfits (e.g. Sayaka has blue hair, blue eyes, and a blue outfit). Homura is the notable exception among the main cast, and is considered a Raven Hair, Ivory Skin-type of beauty.
• Revolutionary Girl Utena: All of the characters that are majorly involved at some point have outrageously colorful hair, highlighting their specialness and importance to the plot. In contrast, most of the background characters, and named characters who are supposed to be more "normal" (like Wakaba, Keiko, Tokiko, and Tatsuya) have brown-black hair. Hair colors include:
  • Utena, Souji: Pink
  • Anthy: Purple
  • Akio, Mamiya, Dios: Lavender
  • Touga: Red
  • Saionji: Green
  • Juri: Orange
  • Nanami: Canary yellow
  • Miki: Light blue
  • Ruka: Dark blue
  • Kozue: Indigo
  • Shiori: Raspberry
  • Kanae: Pale green
  • Mitsuru: Dark yellow
  • Chigusa (from the Sega Saturn game): Teal
• Sailor Moon: Of the main cast alone: Ami/Sailor Mercury has blue hair, Setsuna/Sailor Pluto has dark green hair, Michiru/Sailor Neptune has aqua/light turquoise hair, and Chibi-Usa/Sailor Chibi Moon has bright pink hair that she didn't inherit from either of her parents. Usagi/Sailor Moon, Minako/Sailor Venus and Haruka/Sailor Uranus are all blondes, which is still rather unusual considering how they're all supposed to be fully Japanese. The villains, who are typically from space, have hair in all kinds of colors.
• Shugo Chara!: Main character Amu has pink hair, and most of the Charas have hair in unusual colors (though the Charas' case is justified since they aren't human in the first place). Ikuto and Nadeshiko/Nagihiko have purple hair and Kairi has dark green hair, which could be stylized shades of black.
• Tenchi Muyo!: Ryouko has cyan hair, Ayeka has purple, as does her father, Azusa. Sasami and her mother, Misaki, have light blue, Kiyone has forest green, Washu has a deep red, and at one point we meet a rival Juraian suitor with cotton candy pink hair. This is not treated as anything remarkable.
• Tengen Toppa Gurren Lagann is rife with examples of Anime Hair (including unusual hair colours), since it's an over-the-top, hot-blooded middle finger to science. Heroes Simon and Kamina both have blue hair (though Simon's looks kinda black), Yoko has brick red hair (as does Gimmy), Leeron's is aqua, Darry's is cotton-candy pink, Kittan's is blond and black. Dayakka has green hair, Kiyal has purple hair and Makken has very short light-blue hair-stubs.
• Tokyo Mew Mew: With the exception of Bu-ling Huang/Mew Pudding, all of the magical girls have abnormal hair color; Ichigo (pink), Minto (blue), Retasu (green) and Zakuro (purple). Bu-ling is a blonde.
• In Wotakoi: Love is Hard for Otaku, almost all of the main characters have unusually colored hair; Narumi's hair is pink, Hirotaka's is dark blue, Koyanagi's is green, and Kabakura's is bright orange. Naoya's blond hair is confirmed to be dyed, but aside from that, no one seems to consider the characters' hair colors strange.
• Yokohama Kaidashi Kikou: Human characters have normal hair colors, but robots have hair in more unusual shades. Alpha has green hair and Kokone's is light purple; Maruko's is reddish brown, which wouldn't be out of place elsewhere but stands out in Japan. It's implied to be an in-universe case of Colour-Coded for Your Convenience, as it's highly likely that robots were designed like that on purpose to distinguish them from humans. Another case that stands out is the Osprey, whose hair is a slightly deeper purple than Kokone's.
• Yu-Gi-Oh! has plenty of abnormal hair colors already (the three-toned Yugi and every villain from the silver-haired since childhood Pegasus and the pink-haired Siegfried come to mind), but Yu-Gi-Oh! ZEXAL takes it to new levels by giving everyone two-toned technicolor hair colors.
• Zombie Land Saga: As an Affectionate Parody of idol anime, there's a lot of variety in out-there hair colors. The main characters for example have Sakura (pinkish-red hair), Ai (blue hair), Junko (white hair), Lily (teal hair), and Tae (black-purple hair). A lot of side characters follow similar design cues.

Asian Animation

• Shining Star: We have characters with yellow, blue, pink, and green hair as if it were perfectly normal. This actually cost the Chinese Foreign Remake some air time, as it was pulled from the airwaves after complaints that, for some reason, its hair colors were a bad influence on children.

Fan Works

• Hilda and the howling woods: All werewolves in the setting have unnatural hair colors, meaning Hilda's own heritage was hiding in plain sight.
• Inkopolis Chaos: Due to this story being set in the Splatoon universe the cast has a wide variety of hair colors. Samuel and Bethany have blue, Luke and Jade have green, Sylvia and Georgina have orange, Natalie and Dylan have pink, Melody has pink/purple, Katelin has blue/purple, Ruby and Scarlet's gang have red, Summer and Melissa have yellow, Obsidian and Blakeson have black, Cyalux has light blue and Adelyte has turquoise.
• I Woke Up As a Dungeon, Now What?: Ethnic Velthians (or part-Velthians) apparently have hair in every imaginable color except those that occur naturally on Earth.
• After arriving in Equestria in Manehattan's Lone Guardian, Leviathan is initially confused by the spectrum-spanning coats and manes of the residents. It's later revealed after she's convinced to remove her helmet that her own hair is an ocean blue shade.
• Return to Hinamizawa runs under the assumption that the unusual colours in the source material are natural, and they follow similar inheritance patterns to real hair colours.
• We Are All Pokémon Trainers: Like its main source material, WAAPT has plenty of people with otherwise unnatural hair colors, such as blue and green, which goes without comment, with some being natural and others just being dyed. At least in Mezzo's case, the reason her family has blue hair is at least in part due to her ancestor Andante promoting to Warlord and having her hair turn from brown to blue as a result.

Films — Animation

• Wreck-It Ralph: Many of the Sugar Rush racers have odd hair colours, as befits their confectionery themes and their In-Universe game world's Japanese origin. For example, Minty Zaki has green hair; Snowanna Rainbeau has a rainbow-coloured afro.

Films — Live-Action

• Descendants has the main characters' colour coding extend to hair colour as well as wardrobe, likely inherited from their supernaturally evil parents: Evie has blue hair, Mal's is purple, and Carlos has pure white hair with dark roots.

Live-Action TV

• This was invoked in Code Lyoko: Evolution; since Aelita was the only one in the original show with an unnatural hair color (not counting Odd's purple-dotted blonde hair), she would otherwise stand out pretty hard in the real world, so the decision was made to give a bunch of background extras equally-unnatural hair colors to close any potential plot holes.

Literature

• The Apothecary Diaries: The novels' illustrations show that several characters have unusual hair colors, such as Maomao's dark green hair and Jinshi's purple hair, and no one ever comments on them (though the darker hair colors could be stylized shades of black). The only character whose hair color is considered unusual is Gyokuyou, whose red hair and green eyes mark her foreign ancestry.
• Ascendance of a Bookworm: The very first hint Myne gets that she has reincarnated in a fantasy world is that her mother and sister's hair is naturally green, while her own and her father's is dark blue. The first female friend she makes has bright pink hair and her internal monologue has her admit to liking to spend time around Lutz in part because his hair is a shade of blond that would have been plausible back in her previous life on Earth.
• A Chorus of Dragons: The vané have brightly colored hair in all the shades of the rainbow. The Manol vané tend to have hair in saturated or jewel tones, while the Kirpis vané have hair in paler pastel shades.
• Doom Valley Prep School: While most people seem to have fairly normal hair colours, Naomi has pink hair, and Calci, a Dwarf, has emerald green hair and beard. This is not seen as out of the ordinary or even worth mentioning.
• Most characters in Haruhi Suzumiya have realistic hair colors, though characters who are Humanoid Interfaces stand out for having more unusually-colored hair; Yuki has greyish-purple hair, Ryoko has blue hair, and Kimidori has light green hair. Oddly, Tsuruya has dark green hair as well despite not being a Humanoid Interface herself. No one seems to find these hair colors unusual, even if most of the characters who have them aren't human. This carries over to the spinoff manga The Disappearance of Nagato Yuki-chan, even though it takes place in an Alternate Universe where all the characters are normal humans.
• The hero of the Anime-inspired online serial Magical Girl Policy finds the rainbow spectrum of hair colors common in Kessia City to be completely odd, but the locals think it's a normal to the extent that they even have color designations like bluenette for blue, emerelde for green, violette for purple, and scarlette for blood red. At one point Rob meets a cheerleader with snow-white hair and muses to himself about what they might call that. He dismisses the first name he comes up with (whitehead) for good reason.
• Mushoku Tensei: Jobless Reincarnation: This is a staple for the demon/magical races, which are distinguished by hair color, such as the Supards, like Ruijerd, that have green hair, the Migurds, like Roxy and Lara, that have blue hair, the Dragon Tribe, like Orsted and Perugius, who have silver hair. Many characters also have unusual hair colors, such as purple, blue, pink and green, outside of these broad tendencies.
• My Next Life as a Villainess: All Routes Lead to Doom!: After she was transmigrated into a video-game character, Catarina has seen hair and eyes that were blonde, silver, brown, red, and black after she regained her Past-Life Memories, and thought this trope is played straight in the world of Fortune Lover. So she was puzzled when white-haired and red-eyed Sophia asked her if she thought the latter's looks "disgusting"—Catarina wasn't expecting albinism is a thing here, and albinos are as discriminated here as on Earth, and all the time not only she thought Sophia's feature is normal in this universe, she thought they beautiful to boot.
• Quantum Devil Saga: Avatar Tuner: Hair colors such silver, pink, green and red are all very common. This ends up leading to some confusion regarding Sera, whose black hair is completely unheard of.
• Shadow of the Conqueror: In the fantasy world of Everfall, the people have a wide variety of different hair colours, form blue, to green, and purple.

Tabletop Games

• Exalted: Influence from intense elemental concentrations frequently causes mutations in the people of Creation, the most common of which is unusual hair colors. As such, people from the archipelagoes of the West often have blue, indigo, or purple hair, people in the forests of the East commonly have green hair, people from the deserts of the South have literally red hair, and people from the frozen north often have white or light grey hair. In addition to these colors, which often become as common and established as mundane browns, blondes, blacks and gingers, more unusual shades are also known among people exposed to the mutative energies of the Wyld.
• Infinite Worlds: Cyberme, an anime-flavoured timeline described in Pyramid vol 3 #20, has escaped gene-altering viruses that cause one in fifty births to have unusual hair or eye colors.
• Pathfinder: Gnomes are close kin to fey and often have brightly-colored hair — scarlet, blue, purple, green, yellow, white, and so on — as a result; mundane shades are almost entirely unknown. Elves also more diverse coloring than humans but tend to match their surroundings, so their primary unusual color is green for forest-dwelling elves.
• Traveller: The variant races of humans scattered around space generally have aesthetic differences (and in most cases, non-aesthetic) from those who remained back on Earth. Hair color is sometimes one of them. In particular for this trope, the Pirians have blue or green hair, their follicles concentrating cobalt and copper depending on genetics.

Toys

• Lalaloopsy: While normal hair colors have shown up, the norm in Lalaloopsy Land seems to consist of pink or blue hair. Oddly enough, all of the males have had normal hair colors while it's the girls who show up with the unique ones.
• The My Little Pony figures have manes and tails in every color except for the black/dark brown/off-white found in real-world equines. Pink, hot pink, Barbie pink, magenta, fuchsia, lavender, violet, periwinkle ... colors that have never existed in equine manes or tails pervade the MLP franchise. This extends to the Animated Adaptations, where the fourth generation ponies have Princess Celestia and Princess Luna, with pleochromatic manes.
• Novi Stars: In addition to varying skin tones, each alien girl has oddly colored hair as well.
• Hairdorables mixes this with some selected natural colors. Several characters have bright colors and multicolored hair, including splits and mixes. These colors include blues, greens, pinks, whites, and more. Even the characters with the more "natural" colors - Brit, Skylar, Kat, and Bella - have streaks of other colors blended in their hair.

Video Games

• Alnam no Kiba: Many of the characters have strange hair colors. This includes Tobari and Aika having green hair, Rancho and Koran having dark blue hair, and Ryousui and Mariane having light blue hair. All of the Shitenkou have multicolored hair, such as Seiron having pink hair with blue bangs.
• La Corda d'Oro contains a rainbow of unnatural hair colors. Let's see...Kahoko Hino's bright red, Len Tsukimori's blue, Ryoutarou Tsuchiura and Kazuki Hihara's varying shades of green, Azuma Yunoki's purple, Shoko Fuyuumi's bluish-green, Kanazawa-sensei's reddish purple, Shinobu Ousaki's the other shade of red, and Keiichi Shimizu's blonde.
• In Digital Devil Saga, the girl who fell from the sky is instantly recognizable and keeps the characters in a kind of awe with her bizarre black hair and brown eyes. Fluorescent-red-haired Heat, purple-haired Argilla, and green-haired Gale simply can't understand how a human could have such a strange hair colour.
• A large majority of Disgaea characters, demon or not, have natural technicolor hair ranging from blue to white to neon pink.
• Dislyte: It's common to see Espers with variating shades of unnatural hair colors which fits with their supernatural nature. It ranges from bright red, white, magenta, green, teal, purple, pink and several more. However, as seen with Willy and Sieg who aren't Espers (initially in the latter's case) but still have unnatural hair colors, Espers aren't the only ones that can have these.

• Glimmer In Mirror: Every humanoid characters are fairies, so their hair naturally comes in a variety of colours. The player protagonist Shirro for instance sports turquoise-green hair that glimmers when she's running.
• Hades focuses on Greek mythology, and many of the gods have hair in unusual colors, with the Olympian gods in particular having hair colors that correspond to their abilities. No one finds this unusual, likely because they're gods and not regular humans.
• Harvest Town: Despite being ostensibly set in China, more than half of the town's residents have pink, blue, white, red and blonde hairs. Justified since the town has a salon that dyes hair, and it is all but stated that, at the very least, Sherry and Yau's unusual hair colours come from bottles.
• Jak and Daxter: While there are many characters with normal hair colors, many others sport shades far more exotic. It's particularly common for this to take the form of multicolored hair, such as Jak's hair being green and yellow and Keira's being green and blue.

• Little Flower Fairy: Orange, green, and purple hair, among other colors, can be found on the fairies. This is to establish that they're not human. This was carried over to the video game's TV series, Flower Angel, with the trade-off that some of the humans have wild hair colors as well, such as Xiaoai and Eric with their pink and blue hair, respectively.
• In Lobotomy Corporation, many of the titular company's Sephirot sport a variety of unusual hair colors and all of them correlate to their namesake on the Kabbalistic Tree of Life.

Raffina has pink hair, the Dark Prince, Draco, and Lidelle have green hair, Maguro and Feli have purple hair, Rulue and Sig have blue hair...
• Anthropomorphic characters in Sonic the Hedgehog tend to have all kinds of fur colors.

• Stardew Valley: While most of the villagers have plausible hair colors, several also have odd ones, like Caroline (green), Shane, Jas and the Wizard (purple), and Emily (bright blue). Interestingly, Caroline is dismayed that her daughter Abigail dyes her hair purple, despite being green-haired herself.
• Touhou Project: A large number of characters have brightly-colored hair. While many of these can be explained by most of the characters being some kind of Youkai, a number of humans, such as Sanae and Akyuu, have saturated green or purple hair that's completely taken for granted.
• Trails Series has numerous characters with unusual hair colors. In the The Legend of Heroes: Trails of Cold Steel games, there's the orange hair of Elliot Craig and his family, Laura S. Arseid's purple hair, the pink hair of Emma Millstein and the aqua-blue hair of Millium Orion, to name just a few examples. It's explicitly and repeatedly mentioned that the hair colors we see are the same ones the characters see. In the The Legend of Heroes: Trails from Zero and Trails to Azure games, nobody looks at Lloyd strangely when he asks if anyone has seen a green-haired girl walking around for example and Noel describing her own hair as 'pink-brown' doesn't raise eyebrows either.
• Twisted Wonderland: Multiple characters have hair colors that span an entire rainbow, from red (Riddle), blue (Deuce and the Shroud brothers), green (Trey and Sebek), teal (the Leech brothers) and purple (Chenya), none of which is treated as anything special or bizarre in the setting.

• Xenoblade Chronicles 2's humans^note Plus the Demihumans like the Urayans and Gormotti, which the game also counts as humans usually have fairly standard hair colors, but also throw in silver here and there. In addition, the Blades also throw in a bunch of unnatural hair colors - In the main party alone, Pyra has a bright, unnatural shade of red, Poppi's and Brighid's hair is purple, and Pandoria has green hair. The optional Blades cover most of these colors as well, plus some blue hair for good measure.
• Yandere Simulator has characters with normal hair colours co-existing with students who have technicolor hair with no questions asked.

  • Senpai has black hair by default, but he can be customised at the beginning of the game to have a more unusual hair colour.

Visual Novels

• CLANNAD: The cast runs the gamut of rainbow hair colors...except for Sunohara, whose blonde hair is dyed and is stated to be "an impossible color" (his actual hair color is gray-blue).
• Charon’s characters tend to have unusually-colored hair.
  • Mix Ore has Nagisa and Kantarou as the only characters with strange hair colors. Nagisa has pink hair while Kantarou had grey hair.
  • Most of the characters in The Cradle of Ruin have odd hair colors. Hotarou has dark blue hair, his mother Megi has teal hair, Mikuri has pink hair, and Angelica has purple hair. Averted with Tsuna who had blonde hair.
• Katawa Shoujo: The characters' hair colors, while a little too various for what is at least nominally a Japanese school, tend to remain in the Blonde, Brunette, Redhead spectrum. Dark-haired characters tend to have blue or purple highlights, and their hair colors are listed as such on the homepage. Several side character, on the other hand, have rather unrealistic colors; most notably the nurse, who has blue hair, but there's also both Jigoro (blue) and Hideaki (green), which does stand out a bit from a mainly natural-coloured hair dominance in the game. Misha, who has bright pink hair, is the only character whose hair color is immediately commented upon and is revealed to be dyed in both Lilly's and Shizune's routes; she's actually a natural brunette.
• The cast of Little Busters! is full of characters with unusual hair colors that nobody ever comments on, such as Mio's blue hair, Haruka's magenta hair, and Sasami's purple hair.
• NU: carnival: Most of the clansmen have naturally colorful hair such as pink (Aster), purple (Morvay), light blue (Edmond), green (Olivine) and lavender (Kuya).
• SHUFFLE!: Asa has green hair. Nerine is purple, Primula has silver hair, Sia has a reddish hair color. All are unremarkable within the story.
• Starship Promise: Human hair comes in various colors including blue, green, purple, and silver. Some are the product of dye, while some appear to be natural.
• In Sunrider, some of the characters have relatively normal hair colours but the rest are more exotic. Kayto Shields and his sister Maray both have naturally white hair, as does Sola. Chigara has periwinkle blue hair, as does her Prototype sister Veniczar Arcadius. Kryska has indigo blue hair. Veniczar Fontana has dark purple hair. And Claude has bubble gum pink hair. Nobody comments on any of these hair colours.
• When They Cry
  • Higurashi: When They Cry falls victim to this. Keiichi and Tomitake's hair is brown, unusual for a full Japanese person, while Satoko, her immediate family, and Takano are all blonds (more unusual). Rena and Irie has orange hair, Rika and Chie have blue hair for no adequately explored reason (though Chie is an Expy of Ciel from Tsukihime, who also has blue hair), and the Sonozaki family women have green hair. Naturally, no one ever comments on any of this.
  • Most characters in Umineko: When They Cry have realistic hair colors, but there are exceptions; Battler and his sister Ange have bright red hair, Bernkastel, Erika and Zepar all have blue hair, Dlanor has lavender hair, Chiester 45 and 410 respectively have pink and teal hair, Leviathan has green hair, and Amakusa and Clair both have white hair. Most characters with unusually colored hair aren't human or are magical in some way.
• Your Turn to Die features a veritable rainbow of colors. Q-taro has bright, flaming red hair, while Nao's is a slightly softer shade that's more cardinal. Sara has orange hair that appears more of a soft brunette in some art; Kanna has light green; Sou has teal... but the true standout here is Gonbee/Alice, who pairs bright blue bangs with a magenta and lime green-striped buzzcut.

Web Animation

• Anywhere Astounding Girls: Almost everyone has an unnatural hair color. Within the cast of main characters, Penny is the only one with a "natural" hair color.
• The only characters in AstroLOLogy with hair of a natural color are Leo, whose mane is brown, Aries, who develops brown hair when he takes on a werewolf-like form in "A Hairy Scary Tale", and both Geminis, who are depicted having brown hair in "Life of the Party". Everyone else has hair that's red (Scorpio), blue (Aquarius), pink (Pisces and Cancer), green (Sagittarius), purple (Virgo), or has no visible hair at all (Taurus, Libra, and Capricorn).
• RWBY: Eighty years ago, a terrible global war sought to suppress individuality and artistic expression. In memory of that, people name children after colour associations, and express their personalities through their clothing styles and hair colours in ways that often link in some manner to their Aura colours. Regardless of whether hair colours are natural or not, a wide variety of implausible and impossible colours exist. Impossible examples include:
  • Green hair: Doctor Oobleck, Emerald Sustrai, Russel Thrush, Sage Ayana, Reese Chloris, and Joanna Greenleaf.
  • Blue Hair: Neptune Vasillas, Ciel Soleil, and May Marigold.
  • Multi-coloured hair: Neopolitan (pink, brown, white, after the ice cream of the same name), Nadir Shiko (pink, black)
  • Other colours: Nebula Violette (purple), May Zedong (magenta).

Webcomics

• Aetheria Epics: Normal hair colors for people in Veil include pink, purple, and green. Having black hair can give you away as an outsider.
• Drowtales: The ancient elves often had hair in various unusual shades; one of the few surviving Dokkalfar, Diva'ratrika, had naturally lilac hair. Modern drow have uniformly snow-white hair; however, it's a very common practice among all drow cultures to dye one's hair, either wholly or in more complex patterns, and thus characters on-panel have hair in every shade of the rainbow. It's particularly common, although not universal, to dye one's hair in the colors of one's clan, house, or bloodline, which provides a useful way both in-universe and for viewers to quickly tell who is part of what faction — for instance, most Val'Shargress characters dye their hair scarlet red, while Sil'lice's descendants usually dye theirs blue. A notable exception to this trend is Ariel, who uses her shapeshifting powers to simply make her hair whatever color she wants it to be without resorting to dye.
• El Goonish Shive:
  • As explained here, hair colours like purple, green, and blue are entirely mundane. However, they are considered a scientific anomaly, so magic is probably responsible. When magic changing your hair and/or eye colour is common enough that it's registered as an actual disorder, it makes sense that those hair colours would become commonplace over generations.
  • According to Dan's Twitter account, Tedd's purple hair was intended to be black, but by the time he learned how to paint it without ending up with an ink blob, colors were already established and he liked the idea of this being a natural color.
  • This is brought up in one of the Q&A sessions. Upon reading a question asking whether strange hair colors are natural in the EGS universe, Chika wonders if the person writing it lives in a universe without brown, black, or blonde hair before giving a somewhat hesitant "yes".
• The Far Side Of Utopia: On Malsa (and possibly other places on the world of Palindra), much of the younger cast have unusual hair and eye colors (blue, green, pink, etc.). It's implied this is because many of them are Designer Children, people who were genetically altered from birth to be smarter, stronger and, in some cases, have enhanced and/or unique magical abilites. The odd hair color (and matching eye color) are used as a sign of their status as a Designer Child. It's apparently illegal for them to dye their hair a different color for this reason.
• Kiwi Blitz: Some characters have outlandish hair colors, such as Steffi (pink), Reed (green), Gear (blue), and Steffi's dad's assistant (purple). Given the anime influence, it's easy to assume that these are natural hair colors. However, over time, these are revealed to be the products of hair dye or wigs.
• My Impossible Soulmate: Hair colors like green, purple, etc. seem to be common in the world Chiaki ends up in.
• The Order of the Stick:
  • Blue hair, both light and dark, is common in characters from the Japan-inspired Azure City. Purple or teal hair is also present, although it's rarer.
  • This is also common among elves. Vaarsuvius has purple hair, Inkyrius has light green hair, their children have teal and orange hair respectively, Aarindarius has pink hair and Veldrina has lilac hair.
• Outsider: In addition to their blue skin, the Loroi have hair in every shade of the rainbow — fiery scarlets, bright yellows, greens, light to navy blues and violet have all appeared on-panel.
• Sleepless Domain: While most ordinary civilians have natural hair colors, magical girls undergo a vivid change in hair color upon first awakening their powers. As a result, magical girls can be easily distinguished by their vibrant hues, even when they aren't transformed. Even magical girls with relatively normal hair colors, like Sylvia's golden blonde and Cassidy's bright orange, have more vivid shades than what would be considered natural.
• Station Square: Some characters have what, to us, would be unnatural hair colors, such as green, pink, and purple. Notably, Dahlia's green hair is not pointed out as one of the things that mark her as inhuman.

Web Original

• In the world of Buster Girls you can expect every color from across the rainbow to appear as a natural hair color. The main heroines alone include red, blue, yellow and purple hair to the point the brown-haired Makoto is the one standing out.

Web Videos

• Pop Cross Studios: Five characters in Christian Pearson's "Tales of the Multiverse" series have diverse hair colors. Three of them are Overseers ( Physical Gods) such as Astra, who has green hair shaped like a tree canopy; Ulitus, who has blood-red hair to go with his red eyes to fit his Obviously Evil apperance; and Baroness Elloise Ludum, whose primarily blonde hair ends in magenta and purple tips. For human examples (or Ambiguously Human in Burn's case), there's Pyromaniac Burn, the fire-controlling Dark Action Girl and one of Doctor Eunice Versaille's Co-Dragons, who has orange hair darkening to a red gradient, making her appear to have flaming hair(which goes with her orange skin): and Clayton, the Good Is Not Nice leader of the Predator Coalition of Demon Hunters, who happens to have Mystical White Hair. A less prominent character outside of the Multiverse Tales is Mabel Fern, the Anthropomorphic Personification of mobile phone games ^note  from Christian's "What If Video Game Genres Were Characters?" video , who appears to be a Rose-Haired Sweetie, but is very manipulative when trying to get people to buy her wares.

Western Animation

• Adventure Time: Fionna and Cake: In Fionna's world, most of the magical characters of Ooo are normal humans, but they still often have hair of unusual colours similar to their alternate equivalents, such as Gary having pink hair, Fern having green hair (with flowers in it), and Ellis P. having purple hair. It turns out that Fionna's world is the same Gender-Bent Alternate Universe as the original series but after The Magic Goes Away, and the hair is a remnant of their original forms.
• Several characters from Angelo Rules have exotic hair colours. Angelo's sister Elena and their mother have blue hair, his friend Lola has pink hair, Ethan, Ms. Pearla and Damien Burst have different shades of purple, and the two members of Slobbers have purple and green hair, respectively.
• Batman Beyond: All sorts of colors are common among Terry's classmates, including bright green, bright orange, and pure white. No one thinks this is strange.
• The Owl House: On the Boiling Isles, some witches and demons have natural hair colors that aren't seen in humans — Edric and Emira's hair is dark green, Odalia's is light green, Raine's is teal, Bria's is purple, the Collector's is white, and while Hunter is a natural blond, his hair naturally comes in two distinct colors, light blond on the top, and a darker blond near the bottom. Amity stands out in this regard, as despite being a natural brunette, her mother forces her to dye her hair green to fit in with the rest of her family. Once she starts rebelling against Odalia's influence, she starts dyeing her hair purple instead.
• In The Simpsons, various shades of green, blue, and purple hair are unremarkable, and characters like Bart's friend Milhouse (and his parents), Sherri and Terri Mackleberry (and their parents), Krusty the Clown (and his daughter Sophie), and Krusty's assistant Sideshow Mel (and his wife Barbara) all apparently have their natural colors. Marge's hair, however, isn't natural...because she's Prematurely Grey-Haired and has been dying her hair its original Blue #56 since she was 17. It's a sign of how normal the color is In-Universe that she keeps this fact a deadly secret and everyone's surprised to find it out.
• In Steven Universe, the alien Gems have skin tones and hair colors that match their namesake gem, so they are all over the color spectrum. Examples include pink (Rose), pale purple (Amethyst), blue (Lapis), cyan (Alexandrite), light orange (Pearl), and cherry red (Spinel). The humans, though, have ordinary hair colors. One Season 4 episode features a punk-rock Badass Biker with pink hair, and the technicolor aspect of Gems is lightly lampshaded when Pearl asks Steven if humans "come with pink hair".
• Work It Out Wombats!: Not all of the characters have hair, but if they do, they are in colors such blue, pink, or green.
• Zeke's Pad gives each character an abnormal hair colour, even though Zeke is the only one with a connection to the supernatural. Among the main cast, Zeke and his father Alvin have cerulean-blue hair, Jay has teal hair, Ida has purple hair, Ike has blood red hair, Rachel has light green hair, and Maxine has dark green hair. Seeing that purple-haired Ida and blue-haired Alvin have a redheaded son and a green-haired daughter, hair colour seems to be completely random in this universe, rather than genetic like in real life. However, all of Jay's ancestors in "Family Portrait" are drawn with teal hair, and the same episode's depiction of Zeke's ancestors give them the same hair colours as the present-day members (Idina and Izzy have blue hair, Calvin has purple hair, Raphael has red hair, and Zack has green hair), implying that the modern Palmers inherited their hair colours from them.
