“His use of colour is above all lyrical. He feels colours and he reveals his feelings through colours; he does not see them in isolation. He does not just see yellow, red and blue and violet; he sees sorrow and screaming and melancholy and decay.”

—Sigbjorn Obstfelder, on Edvard Munch, 1893; quoted by John Gage in Color in Art, 2006. Pictured above is The Lonely Ones (Two Human Beings), an Edvard Munch woodcut print from 1899.
