It was always disappointing to see that what I could really master in terms of form boiled down to so little.

In every work of art the subject is primordial, whether the artist knows it or not. The measure of the formal qualities is only a sign of the measure of the artist's obsession with his subject; the form is always in proportion to the obsession.

The object of art is not to reproduce reality, but to create a reality of the same intensity.

(Art is) the residue of vision.

I've tried doing so, for it was never my intention to paint only with gray. But in the course of my work I have eliminated one color after another, and what has remained is gray, gray, gray!

If I see everything in gray, and in gray all the colors which I experience and which I would like to reproduce, then why should I use any other color?

That's the terrible thing: the more one works on a picture, the more impossible it becomes to finish it.
