I've been forty years discovering that the queen of all colors is black.

Whoever wishes to devote himself to painting should begin by cutting out his own tongue

Purer colors... have in themselves, independently of the objects they serve to express, a significant action on the feelings of those who look at them.

It is not enough to place colors, however beautiful, one beside the other; colors must also react on one another. Otherwise, you have cacophony.

Color, even more than drawing, is a means of liberation.

Don't try to be original. Be simple. Be good technically, and if there is something in you, it will come out.
