The story goes that one day when Cézanne was picknicking in the country with some friends and a collector, the latter suddenly realized that he had dropped his overcoat somewhere on the way. Cézanne raked the landscape with his gaze, then exclaimed: ‘I’ll swear that black over there doesn’t belong to nature!’ Sure enough, it was the overcoat.

— André Malraux, The Voices of Silence, 1978
