Anime Hair colors can run the entire spectrum and then some, only limiting themselves to the "natural" range in the most serious of series. One reason, it is claimed, is that it helps the viewer distinguish characters who might otherwise be hard to tell apart in a show with budget-saving simple designs. This in turn makes the character more easily copyrightable. Subtler variations of the hair could work, but these are usually avoided because they are difficult to animate.
