All methods are sacred if they are internally necessary. All methods are sins if they are not justified by internal necessity.

Color is the keyboard. The eye is the hammer. The soul is the piano, with its many strings.

Each color lives by its mysterious life.

It is essential that the painter should develop not only his eyes, but also his soul, so that it too may be capable of weighing colors in balance.

Every artist, as child of his age, is impelled to express the spirit of his age.

The eyes are hammers.

Color cannot stand alone.
