Alien Armpit — Perhaps the most unusual color name on this list, Alien Armpit is a limited edition color produced by the Crayola crayon company. The yellow-green hue is a playful nod to the classic alien imagery of "little green men" and was discontinued in the late 1990s, so it has no match in Crayola's current crayon catalog.
