Like many insects, flies are most sensitive to green light. This means that they would see their world as 'black and white,' in that they can't see the multiple colors required to reconstruct a color image of the world. They do, however, have specialized cells that enable them to see ultraviolet wavelengths.

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.

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.

People usually consider walking on water or in thin air a miracle. But I think the real miracle is not to walk either on water or in thin air, but to walk on earth. Every day we are engaged in a miracle which we don't even recognize: a blue sky, white clouds, green leaves, the black, curious eyes of a child -- our own two eyes. All is a miracle.
