I must tell you that your letter [of Pissarro] surprised me at L'Estaque on the seashore... I have started two little motifs with a view of the sea; they are for monsieur Chocquet who spoke to me about them. – It is like a playing card – red roofs near the blue sea. The sun is so terrific here that it seems to me as if the objects were silhouetted, not only in black and white, but in blue, red, brown and violet. I may be mistaken, but this seems to me to be the opposite of modeling.. [to reduce the pull of perspective to the horizon]

In his letter (early Summer of 1876) to Pissarro; as quoted in Impressionism and Post Impressionism 1874 – 1904, Linda Nochlin, Englewood Cliffs, New Yersey, 1966, p. 87
