The importance of colour is as nothing compared with that of form, chiaroscuro and arrangement. They are the true and enduring bases of pictorial art.
The amount of chiaroscuro an idea harbors is the only index of its profundity.
No one can live in the light all the time.
Our mind is the canvas on which the artists lay their colour; their pigments are our emotions; their chiaroscuro the light of joy, the shadow of sadness. The masterpiece is of ourselves, as we are of the masterpiece.
