When I am finishing a picture I hold some God-made object up to it -- a rock, a flower, the branch of a tree or my hand -- as a kind of final test. If the painting stands up beside a thing man cannot make, the painting is authentic. If there's a clash between the two, it is bad art.
When I judge art, I take my painting and put it next to a God made object like a tree or flower. If it clashes, it is not art.
All colors are the friends of their neighbors and the lovers of their opposites.
