A Subtrope of RuleOfSeven

* [[http://en.wikipedia.org/wiki/Zayin]] is the 7th letter in most Semitic abjads (writing system). It is the source of both the modern "7" and "Z", and also meant "sword" (several proto-versions look like basic swords, and the Arabic derivation bears a slight resemblance to a scimitar).

->SevenDeadlySins, seven ways to win\\
Seven holy paths to hell and your trip begins\\
Seven downward slopes, seven bloodied hopes\\
Seven are your burning fires seven your desires...
-->-- '''IronMaiden'''', "[[http://www.youtube.com/watch?v=A0Yn72QM-lg Moonchild]]"

The joke of this is, he missed a real seventh colour: cyan, between green and blue.
