It is only after years of preparation that the young artist should touch color - not color used descriptively, that is, but as a means of personal expression.

The splitting up of color [as Impressionists did] brought the splitting up of form and contour . . . Everything is reduced to a mere sensation of the retina, but one which destroys all tranquility of surface and contour. Objects are differentiated only by the luminosity that is given them.

Do remember that one line does nothing; it is only in relation to another that it creates a volume.

In art, truth and reality begin when one no longer understands what one is doing or what one knows, and when there remains an energy that is all the stronger for being constrained, controlled and compressed.

Color helps to express light, not the physical phenomenon, but the only light that really exists, that in the artist's brain.

Simple colours can affect the intimate feelings with all the more force because they are simple.

A painting in an interior spreads joy around it by the colors, which calm us.
