Disney often uses Lime Green to represent evil, and villains call everybody "Fools!" a lot.
I loosely intend to use puke green vs orange, as well as two different shades of purple, for good and evil, for the one project that uses actual visuals.
Come to think of it, Harry Potter tends to use red for good and green for evil, with the exception that Harry has green eyes and Voldemort has red eyes.
And I would definitely use pink for evil. When I think pink, I think the color of a squashed mosquito after it's already sucked some of your blood.
