I paint the way I spread butter on pumpernickel.

When we are honest - that's my saying - if we are honest then we will reveal ourselves. But we do not have to make an effort to be individualistic, different from others.

Repeated similar experiments with adjacent colors will show that any ground subtracts its own hue from colors which it carries and therefore influences.

I think Kandinsky and I were very near friends.

Simultaneous contrast is not just a curious optical phenomenon - it is the very heart of painting.

We never really perceive what color is physically!

Instead of art I have taught philosophy. Though technique for me is a big word, I never have taught how to paint. All my doing was to make people to see.
