there was this one guy who used to work at my company who was colorblind. he had to have someone label the color of his clothes for him and make note of which shirt goes with which pants because he had no way of telling at all.

i remember in physiological psychology when we were learning about the optical nerve, color is divided into rods and cones and the way your cortex translate the rods and cones is through contrast and light. or something like that. correct me if i'm wrong...it's been a while.

we know a color, red for an example is red because we learned that particular color is red.

 

There was an old BC comic strip in which I believe BC and Peter were discussing how people see colors. The dialogue went somehing like this:

Peter: I wonder if people see colors the same. I might call something gray and you will call it gray because that's what we have been taught is the name of the color, but we might see them differently.

BC: That's ridiculous! Everyone sees colors the same.

Peter: I don't think so, and I'll prove it to you. See that rock over there? What color is it?

BC: Brown.

Peter: Wrong.

 

Color blindness is usually males because the gene is an x linked recessive gene. For those who are not geneticists, that means that it makes the gene in an interesting place.

Men who have the gene will express it because they only have one x chromosome and hence no other x with a dominant gene to keep it from being expressed.

Women who have it will only express the gene if they have two of the recessive genes because they have 2 x chromosomes.

For a man to get it it has to come from his mother, so his mother has to have the gene.
If the mother does not have the gene and the father is color blind, the son won't be, but the daughter of that marriage will be a carrier.

 

Was that english?
