Colour-blindness always extends to the complementary colours. Those who are red blind are also green blind; those who are blind to blue have no consciousness of yellow. This law holds good for all mental phenomena; it is a fundamental condition of consciousness.

Tell [Père] Tanguy to send me some paints. What I need most are ten tubes of white, two of chrome yellow, one bright red, one brown lac, one ultramarine, five Veronese green, one cobalt j I have on hand only one tube of white ... I expect to begin to paint again from nature, and I need the colors.
Camille Pissarro
P.S. If you happen to see Seurat or if you write to Signac, tell them that I have tried the mixture of cadmium (well recommended by Contet), with red, white and Veronese green. It becomes black in four or five days from the Veronese green. Even blacker than the chrome yellow mixture. Tell this to Contet.
