History AdaptationDyeJob / MarvelUniverse

* Granted, the first two people to hold the [[ComicBook/TheAvengers Swordsman]] identity, Jacques Duquesne and Phillip Javert, did have black hair, but the Swordsman of ''ComicBook/HeroesReborn'', who's also a noirette, falls under this due to being revealed to be his reality's ComicBook/{{Deadpool}}, who was originally blond.
* ''ComicBook/CaptainAmerica'': Due to wearing his mask all the time or actually having a literal SkullForAHead depending on the comic, the Red Skull's hair color is depicted inconsistently. Earliest versions of Skull's backstory depict him as blonde, while a 1960s story arc in which he [[GrandTheftMe switches bodies with Captain America]] shows the hair as black, though it has Cap narrate that he somehow made it "much darker" while disguising in the case that somebody actually knew what Skull's face looked like. Creator/Greg Pak's ''Red Skull: Incarnate'' depicts Skull's hair as red, and his hair appears to be black when the mask is partially broken by Magneto in ''ComicBook/AvengersVsXMen''.

** In some of the original myths, [[Characters/TheMightyThorThorOdinson Thor]] is a FieryRedhead (others do actually have him as a blonde), something the lesser-known Creator/DCComics ''ComicBook/NewGods'' version of the character reflects. This is [[JustifiedTrope justified]] by the cyclic nature of Ragnarok in the Marvel Universe: each time Thor is reborn, minor details are changed. The Thor of previous Ragnarok cycle did have red hair, but the Thor we know is blonde. Stan Lee and Jack Kirby may have been inspired by the very popular 1872 painting ''Art/ThorsFightWithTheGiants'' by Mårten Eskil Winge which depicts a blonde clean-shaven Thor eerily similar to the Marvel version.

* ComicBook/{{Storm}}'s eyes are blue in the comics, but in the movie-verse, they're brown because Creator/HalleBerry refused to wear contacts.[[note]]Notably, she's the only exception: ComicBook/{{Sabretooth}}'s Tyler Mane, Toad's Creator/RayPark, ComicBook/{{Nightcrawler}}'s Creator/AlanCumming and ComicBook/{{Mystique}}'s Creator/RebeccaRomijn all wore coloured contacts.[[/note]]
* In the comics, ComicBook/{{Magneto}} has been shown to have had white hair for the vast majority of his adult life, presumably as a side-effect of his mutation (or just as likely due to the [[PrematurelyGreyHaired trauma]] of [[UsefulNotes/TheHolocaust Auschwitz]]). In the films, he's introduced with ''grey'' hair (though only because, lacking ComicBookTime, the screenwriters had to make him the realistic age of a Holocaust survivor), and he has [[TallDarkAndHandsome dark brown hair]] as a younger man in the [[Film/XMenFirstClass First]] [[Film/XMenDaysOfFuturePast Class]] [[Film/XMenApocalypse trilogy]].

* Creator/LievSchreiber's ComicBook/{{Sabretooth}} in ''Film/XMenOriginsWolverine'' has short black hair rather than the long blonde mane from the comics and first movie which Tyler Mane appropriately rocked.
* Creator/TaylorKitsch's ComicBook/{{Gambit}} from the same movie has normal blue eyes unlike the comics where he's got red irises and black sclera. Whether this due to Kitsch refusing to wear contacts like Halle Berry or just a production oversight is unknown. Although when first using his [[HavingABlast power]] to attack Wolverine in the film, his irises do go red briefly.

* ComicBook/{{Psylocke}}'s hair is purple in the comics, but her film counterpart is raven-haired with purple highlights.
* Pre-Deadpool Wade Wilson is depicted as a brunet instead of a blond.

* Though her hair [[PowerDyesYourHair changes to its traditional black color when in her Madame Masque persona]], Whitney Stane has blond hair in ''WesternAnimation/IronManArmoredAdventures''. Abigail Brand also has black hair in the series instead of her trademark green.

* In the original ''ComicBook/TheAvengers'' comics, Princess Ravonna had red hair. In ''WesternAnimation/TheAvengersEarthsMightiestHeroes'', she has black hair and is made AmbiguouslyBrown to boot.
* ComicBook/{{Dazzler}} was a redhead rather than a blonde in ''WesternAnimation/XMenTheAnimatedSeries''.
* ''WesternAnimation/TheMarvelSuperHeroes'' did this to the [[ComicBook/TheIncredibleHulk Hulk]] and ComicBook/IronMan. The cartoon depicting Hulk's origin made him his standard green instead of the gray he was when he first transformed. As well, a few cartoons sporting Iron Man's Golden Armor was recolored to match his modern day red and gold scheme.
* ''WesternAnimation/TheIncredibleHulk1982'' changed Rick Jones' hair color from brown to blond.
* Betty Ross is a blonde in ''WesternAnimation/TheIncredibleHulk1996'', despite being a brunette in the comics.

* Due to wearing his mask all the time or actually having a literal SkullForAHead depending on the comic, ComicBook/RedSkull's hair color is depicted inconsistently. Earliest versions of Skull's backstory depict him as blonde, while a sixties story arc where he [[GrandTheftMe switches bodies with Captain America]] shows the hair as black, though it has Cap narrate that he somehow made it "much darker" while disguising in the case that somebody actually knew what Skull's face looked like. Creator/Greg Pak's ''Red Skull: Incarnate'' depicts Skull's hair as red, and his hair appears to be black when the mask is partially broken by Magneto in ''Avengers vs. X-Men''.
* ''ComicBook/TheMightyThor''

* [[ComicBook/Agent13 Sharon Carter]] has red hair in the ComicBook/{{Ultimate|Marvel}} universe, rather than blond.
* ''ComicBook/UltimateXMen'': Nightcrawler's fur and hair go from blue to black (then, later on, it gets dyed back to blue).

* AdaptationDyeJob/XMenFilmSeries

* ''ComicBook/FantasticFour'': Johnny Storm went from blond to brown hair when they brought ''Film/{{Fantastic Four|2005}}'' to film. Ben Grimm went from brown-haired to bald.

* ''{{Series/Legion|2017}}'':

* ComicBook/{{Iceman}} went from brown hair to blond when animated for ''WesternAnimation/SpiderManAndHisAmazingFriends'' and ''WesternAnimation/WolverineAndTheXMen2009''.

* In the 1978 ''[[WesternAnimation/TheFantasticFour1978 Fantastic Four]]'' cartoon, Lockjaw had white fur instead of brown.
* The Kree Supreme Intelligence is almost always green...except for the time he appeared in the ''WesternAnimation/SilverSurfer'' cartoon, where he was inexplicably colored red.

* [[ComicBook/HumanTorch Johnny Storm]] went from blond to brown hair when they brought ''Film/{{Fantastic Four|2005}}'' to film. Ben Grimm went from brown-haired to bald.

** Marvel's version of the goddess Sif has black hair, rather than gold; this was because [[Myth/NorseMythology the myth]] of ComicBook/{{Loki}} shearing her head in her sleep and having to replace it was changed in this version. Like in the original mythology, he commissioned the dwarves to forge new hair, but didn't pay them what he originally promised. Thus, instead of golden hair, they made black hair to spite him. (Fortunate, Thor thought Sif looked even more beautiful as a brunette, so it all ended well.)

* Though her hair [[PowerDyesYourHair changes to its traditional black color when in her Madame Masque persona]], Whitney Stane has blond hair in ''WesternAnimation/IronManArmoredAdventures''. Abigail Brand also has black hair instead of her trademark green.

* In the '60s ''WesternAnimation/{{The Fantastic Four|1967}}'' cartoon, ComicBook/{{Galactus}} had green skin and a suit of blue armor instead of pink skin and purple armor.

** The original Gabrielle Haller is raven-haired with brown eyes, whereas the show's Gabrielle Xavier [[note]]her maiden name is never mentioned onscreen, but it's unlikely to be Haller because she's Romani in the TV series instead of Jewish like in the comics, and David's surname Haller has been changed to be from his adoptive family. After Gabrielle marries Charles Xavier, her name becomes Gabrielle Xavier, and she's addressed as such[[/note]] is brown-haired with green eyes.

** The comic book version of Charles Xavier is blue-eyed and was blond before he went bald, but the TV iteration has green irises and dark brown hair. The latter is a deliberate nod to the ''Film/XMenFilmSeries'', where the younger Professor X is a brunet as well.

** The comic book version of Charles Xavier was blond before he went bald, but his TV counterpart has dark brown hair. This is a deliberate nod to the ''Film/XMenFilmSeries'', where the younger Professor X is a brunet as well.

** The comic book version of Charles Xavier was blond before he lost his hair, but his TV counterpart has dark brown hair. This is a deliberate nod to the ''Film/XMenFilmSeries'', where the younger Professor X is a brunet as well.

** [[Characters/MarvelComicsLoki Loki]] is a brunette in the marvel comics, redhead in the original myths.

* ''Series/Legion2017'':

** In the comics, David Haller has black hair, but in the show, it's very light brown. It's also more normal and realistic than the towering AnimeHair he has in the source material.
