Painting color from a non-colored object has been a big challenge to me. I have tried and tried many times painting a white cup, but I don't think I have got it. This one is another try. I stared at this stupid cup for about two hours, and I really did not see much colors from it. But I don't want to do another value painting any more. So you see quite a few colorful grays on the cup. Those are colors in my mind. I will keep trying until I figure out how the color of grays are formed on a neutral color object. If you know the trick or you know some one is good at it, please help me out.
