20 Minute Skull study

This was a really quick light study I did last night while watching "Cat on a Hot Tin Roof" with my girlfriend Angela. I did it over an old color comp, 8"x10" on masonite. I'd been wanting to paint the neat little ceramic skulls Ang bought for me last Halloween, so I covered my desk lamp with yellow felt and gave it a shot. This most likely will not be the last color sketch I put up with these little guys.Though the light side of the skull looks like a cold yellow green, I used only Cadmium yellow and white. The old painting underneath was a mostly green composition, and my thin painting allowed the colors underneath to show through, creating the glowing green effect. It was also quite an adventure trying to mix correct colors in a relatively dark room, my main light being bright yellow. Good practice, though SPpOOooooooooOOKKY!
