"The painter goes through states of fullness and evacuation. That is the whole secret of art. I go for a walk in the forest of Fontainebleau. I get 'green' indigestion. I must get rid of this sensation into a picture. Green rules it. A painter paints to unload himself of feelings and visions. People seize on painting to cover up their nakedness. They get what they can wherever they can. In the end I don't believe they get anything at all. They've simply cut a coat to the measure of their own ignorance. They make everything, from God to a picture, in their own image. That is why the picture-hook is the ruination of a painting. ."

“For a long time I limited myself to one colour — as a form of discipline.”

“The more technique you have, the less you have to worry about it. The more technique there is, the less there is.”

“The smell of opium is the least stupid smell in the world.”

“I also often hear the word 'evolution'. Repeatedly I am asked to explain how my painting evolved. To me there is no past or future in my art. If a work of art cannot live always in the present it must not be considered at all. The art of the Greeks, of the Egyptians, of the great painters who lived in other times, is not an art of the past; perhaps it is more alive today than it ever was. Art does not evolve by itself, the ideas of people change and with them their mode of expression.”

“I would like to manage to prevent people from ever seeing how a picture of mine has been done. What can it possibly matter? What I want is that the only thing emanating from my pictures should be emotion. .”

“I deal with painting as I deal with things, I paint a window just as I look out of a window. If an open window looks wrong in a picture, I draw the curtain and shut it, just as I would in my own room. In painting, as in life, you must act directly.”
