If the human race were genetically color blind, how would it effect our concepts of "reality".
This is a potentially interesting question with respect to the "embodied cognition" hypothesis discussed on the "independent reality" thread.
(For the purposes of this discussion, I define "color blind" as being confined to the "black-grey-white" continuum)
Its very difficult to quantify because it's so engrained. Such as traffic lights? In a black, gray and white world that's all you have to pick from, they would probably function different.
Or painting of homes or walls. Three choices of shades between black and white don't offer much variety.
I think many things would be different, even language would be different. Style of clothing, shoes, art, movies, ext would all be different.
