Amazing post! I've always found color-blindness to be a fascinating subject along this line. I first heard about it when a classmate of mine talked about it in a science project of his - his younger brother was colorblind.

Later, I met a woman who was colorblind and I finally got to ask a crazy question of her - the fact that 3D glasses don't really work on someone who is colorblind!

Great post!
