"Allow me to repeat what I said when you were here: deal with nature by means of the cylinder, the sphere and the cone, all placed in perspective, so that each side of an object or a plane is directed towards a central point. Lines parallel to the horizon give breadth, a section of nature, or if you prefer, of the spectacle spread before our eyes by the 'Pater Omnipotens Aeterne Deus'. Lines perpendicular to that horizon give depth. But for us men, nature has more depth than surface, hence the need to introduce in our vibrations of light, represented by reds and yellows, enough blue tints to give a feeling of air."

“And art puts us, I believe, in a state of grace in which we experience a universal emotion in an, as it were, religious but in the same time perfectly natural way. General harmony, such as we find in colour, is located all around us.”

“Maybe Delacroix stands for Romanticism. He stuffed himself with too much Shakespeare and Dante, thumbed through too much Faust. His palette is still the most beautiful in France, and I tell you no one under the sky had more charm and pathos combined than he, or more vibration of colour. We all paint in his language, as you all write in Hugo's.”

“He hits of the tone.. ..but his work lacks unity and temperament too.”

“I'd like to combine melancholy and sunshine.. .There's a sadness in Provence which no one has expressed; Poussin would have shown it in terms of some tomb, underneath the poplars of the Alyscamps.. .I'd like to put reason in the grass and tears in the sky, like Poussin.. .You really need to see and feel your subject very clearly, and then If I express myself with distinction and power, there's my Poussin, there's my classicism..”

“Colour, if I may say so, is biological. Colour is alive and colour alone makes things come alive.. .Without losing any part of myself, I need to get back to that instinct, so that these colours in the scattered fields signify an idea to me, just as to them they signify a crop. Confronted by a yellow, they spontaneously feel the harvesting activity required of them, just as I, when faced with the same ripening tint..”

“Colour is the place where our brain and the universe meet. That's why colour appears so entirely dramatic, to true painters. Look at Sainte-Victoire there How it soars, how imperiously it thirsts for the sun!. .For a long time I was quite unable to paint Sainte-Victoire; I had no idea to go about it because, like others who just look at it, I imagined the shadow to be concave, whereas in fact it's convex, it disperses outward from the center. Instead of accumulating, it evaporates, becomes fluid, bluish, participating in the movements of the surrounding air. Just as over there to the right, on the Pilon du Roi, you can see the contrary effect, the brightness gently rocking to and fro, moist and shimmering. That's the sea.. ..That's one needs to depict. What one needs to know. That's the bath of experience, so to speak...”
