Recently, I was looking at an excellent site that shows those of us who see normal colors what a color blind person sees. See below:
normal vision
[most common form of color blindness] deuteranomaly (reduced sensitivity to)/deuteranopia (unable to perceive) green light
protanomaly (reduced sensitivity to)/protanopia (unable to perceive) red light
[rare from of color blindness] tritanomaly (reduced sensitivity to)/tritanopia (unable to perceive) blue light
Fascinating, enlightening, eh? See here or here for more info.

Very interesting. I enjoyed the photos. I've always wondered what it might be like. It really is fascinating. And I bet fun for you to study!
Interesting. How do they know what it looks like for color blind people?
Nice. I wondered what it must have been like to be color blind or blind to different shades of color. Vance
Angie, I think that since they know that color blindness is caused by weak cones or a lack of certain cones, and certain cones perceive different types of light, they can take a photo and use a lens to cancel out the red, green, or blue light, thus creating what a color blind person sees. I showed these photos to a color blind person and sure enough, the normal photo and one of the color blind photos (according to the type of light the person has a hard time perceiving or cannot see at all) looked the same. So interesting.
