Much of the beauty that arises in art comes from the struggle an artist wages with his limited medium.

Do remember that one line does nothing; it is only in relation to another that it creates a volume.

The use of expressive colors is felt to be one of the basic elements of the modern mentality, an historical necessity, beyond choice.

An artist must not feel under any constraint.

From the moment I held the box of colors in my hands, I knew this was my life. I threw myself into it like a beast that plunges towards the thing it loves.

The essential thing is to work in a state of mind that approaches prayer.

I have always sought to be understood and, while I was taken to task by critics or colleagues, I thought they were right, assuming I had not been clear enough to be understood. This assumption allowed me to work my whole life without hatred and even without bitterness toward criticism, regardless of its source. I counted solely on the clarity of expression of my work to gain my ends. Hatred, rancor, and the spirit of vengeance are useless baggage to the artist. His road is difficult enough for him to cleanse his soul of everything which could make it more so.
