The great black and white draftsman, the sculptor, and the blind man know that form and color are separate. The form itself is what the blind man knows...Color is surface skin that fits over the form.

Every good picture leaves the painter eager to start again, unsatisfied, inspired by the rich mine in which he is working, hoping for more energy, more vitality, more time - condemned to painting for life.

Color is like music. The palette is an instrument that can be orchestrated to build form.

A good drawing has immense vitality because it is explanatory. In a good drawing even its faults have become virtues.

Consistency is the quality of a stagnant mind.

The important thing is to keep on drawing when you start to paint. Never graduate from drawing.

...in the habit of watching every bit of human life I can see about my windows, but I do it so that I am not observed at it.
