The essential thing is to spring forth, to express the bolt of lightning one senses upon contact with a thing. The function of the artist is not to translate an observation but to express the shock of the object on his nature; the shock, with the original reaction.

The chief function of color should be to serve expression as well as possible.

My curves are not crazy.

I cannot copy nature in a servile way; I am forced to interpret nature and submit it to the spirit of the picture. From the relationship I have found in all the tones there must result a living harmony of colors, a harmony analogous to that of a musical composition.

Slowly I discovered the secret of my art. It consists of a meditation on nature, on the expression of a dream which is always inspired by reality. With more involvement and regularity, I learned to push each study in a certain direction. Little by little the notion that painting is a means of expression asserted itself, and that one can express the same thing in several ways. Exactitude is not truth, Delacroix liked to say.

When I paint green, it doesn't mean grass; when I paint blue, it doesn't mean sky.

I am unable to make any distinction between the feeling I get from life and the way I translate that feeling into painting.
