A thimbleful of red is redder than a bucketful.

It has bothered me all my life that I do not paint like everybody else.

My pictures are made up of four or five colors that collide with one another.

If drawing belongs to the world of spirit and color to that of the senses, you must draw first to cultivate the spirit.

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.

I never retouch a sketch: I take a canvas the same size, as I may change the composition somewhat. But I always strive to give the same feeling, while carrying it on further.

A picture must possess a real power to generate light and for a long time now I've been conscious of expressing myself through light or rather in light.
