re: #206 windsagio
also being evil LITERALLY turns you ugly.
Diana Wynne Jones provides a color guide, so you can tell if people in fantasy novels are good or bad by checking their hair and eye colors.
(Red eyes indicate that you are very bad indeed. Red hair generally indicates magical ability and stubborness.)
She adds to this that you should not rely on this guide in our own world, as you are apt to be very disappointed.
