An artist must not feel under any constraint.
An artist is an explorer.
...I am driven on by an idea that I really only grasp as it grows with the picture.
When I put a green, it is not grass. When I put a blue, it is not the sky.
I am curious about color as one would be visiting a new country, because I have never concentrated so closely on color expression. Up to now I have waited at the gates of the temple.
Instinct must be thwarted just as one prunes the branches of a tree so that it will grow better.
