Colour in Literature

I'm fascinated by descriptions of colour in literature. One of my favorite authors is Kim Stanley Robinson, who wrote a sci-fi trilogy called "Red Mars", "Blue Mars" and "Green Mars". Here is a quote from Red Mars:

"Now the sky was a maroon dome, the high clouds the pink of moss campion. Stars were popping out everywhere, and the maroon sky shifted to a vivid dark violet, an electric color that was picked up by the dune crests, so that it seemed crescents of liquid twilight lay across the black plain."
