There are two things in the painter, the eye and the mind; each of them should aid the other.

I paint as if I were Rothschild.

Art first of all is optical. That's where the material of our art is: in what our eyes think.

You must think. The eye is not enough; it needs to think as well.

I have not tried to reproduce nature; I have represented it.

Keep good company - that is, go to the Louvre.

There is a logic of colors, and it is with this alone, and not with the logic of the brain, that the painter should conform.
