My choice of colors does not rest on any scientific theory; it is based on observation, on feeling, on the experience of my sensibility. Inspired by certain pages of Delacroix, an artist like Signac is preoccupied with complementary colors, and the theoretical knowledge of them will lead him to use a certain tone in a certain place. But I simply try to put down colors which render my sensation.
Henri MatisseIf drawing belongs to the world of spirit and color to that of the senses, you must draw first to cultivate the spirit.
