[Mostly Marvel, but some DC] Why do so many villains wear purple and green?

Galactus, Green Goblin, Kang the Conqueror, Mysterio, the Joker, the Riddler, the Leader is pretty green, Magneto (no green, but plenty of purple), Dr. Doom (no purple, but plenty of green)...and I'm sure I'm missing some others. Anyone have any good ideas why all of these baddies prefer green and purple?

My working hypothesis is that it's to balance out the overabundance of red and blue in the superheroes' uniforms, but I was wondering what others had to say about it...?

Purple it a color traditionnally associated with royalties. It instinctively give a feeling of power and authority. Therefore, villains who often aim at controlling the world are naturally attracted to thsi color.

Green on the other hand is a color that reflect greed and envy. Feelings also very strongs amongst villains.
