colors and the brain

Submitted by hlee01 on Fri, 04/10/2009 - 4:07pm.

I thought it was really interesting how we only have three cones that allow us to see infinite number of colors. My question is then what happens when you only have two cones or just one? My guess would be that you would be able to see only limited number of colors. Another question is how color blindness works? Also, are there people who cannot see yellow but see two separate colors instead?
