When thinking of seeing I first think of color rather then shape in my environment. I was surprised to learn that color vision came relatively late in our evolutionary tieline. We had grasping hands and forward facing eyes before we had the ability to see in color. No one is entirely certain why we developed the ability to see in color, some think that it aids in depth perception, others think that it was a way to distinguish between fruit that is underdeveloped and ripe. One professor even hazarded the guess that it had something to do with flowers.

In any event we still see primarily in line and black and white, we notice the outline of things first then fill in the colors in a somewhat haphazard fashion. what does color ad to our world now? What would it be like to be color blind or to have never developed the ability to see color in the first place? How does color change the way we feel, think and interact with our environment?
