"For me, a colour is a force. My pictures are made up of four or five colours that collide with one another, and the collision gives a sense of energy. When I put green, it doesn't mean grass. When I put blue, it doesn't mean sky." Henri Matisse.
"I'm rather inclined to depression and sometimes see everything in black … The biggest worry was losing my love of work. I can put up with the blackest despair by whistling or singing." Henri Matisse.
