More Color

I found the question of whether color is an aspect of physical reality or just made up by the nervous system to be really interesting. Although color is a function of the overlap of different wavelengths, it does seem as though it is a physical reality. When we open our eyes, we generally see the same colors as we saw yesterday, without too much deviation. Colors are just like edges when helping us to define different aspects of our world.
