Color deceives continuously.

The purpose of art is to re-present nature, not represent it.

Abstraction is real, probably more real than nature.

We never really perceive what color really is, as it physically is. This fact makes color the most relative medium in art.

Just as the unmusical ear is not competent to judge music, so it is likewise with pictures, whether they are paintings, drawings or photos. Only a sensitive and trained eye gives us the right to judge.

What has been said does not simply belong to us.

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