Color vision and Art

Color vision and Art is a site about color theory and the way we see and respond to color. It is fun to read and concise without being simplistic. There are also interactive examples so you can experiment with certain effects for yourself. I wondered who wrote all this and then found a credits page with art historians and neuro biologists. It's well worth a visit.
This site led me to another interesting one called Causes of Color. this goes into detail about why things are a certain color. Some of this involves a lot of physics which gets a bit complicated (well for me, anyway) but it's still fascinating.
