[Marvel] Why are so many Marvel villains either green, purple, or in some cases both?

I can't answer as well for green, but purple is naturally associated with a sense of wealth and royalty (There's an interesting anecdote about rare sea snails used for the fabric dye back in the day that caused that association). Most villains tend to be egotists with senses of superiority and i think the purple tends to match that.
