I sculpted a small unicorn head -- not just any unicorn but an angry, dangerous unicorn. So I don't want to paint it the same old unicorn-white. I want something very different from normal horse-colors. And I don't want to paint it just one solid color, either. Oh, and it's to be mounted on a glass rod in a block of soapstone (which is light gray and white with a bit of a greenish cast -- looks kinda' marble-y).
So... any cool ideas? If I use your idea, the winner will get to... uh... see his/her cool suggestion painted on my unicorn!
