That's an interesting question. Eye color
does not make a difference in the colors that a
person sees. There are two different kinds of
color (called "pigment")involved and they are in
two different places.
What we see as eye color is the color of the
iris, which opens or closes to control the
amount of light that gets into a person's eye.
The more pigment a person has in their iris, the
darker their eye is. A person with blue eyes
has no pigment in his or her iris.
The other kind of pigment is deep inside the
eye within the retina, which is the part
that actually picks up light and sends messages to
the brain. The parts of the retina that receive
the light are called photoreceptors.
One type of photoreceptor is called a rod
and it only lets us see black and white. Rods
work well even when it's pretty dark. Cones
let us see color, but only if they have the
right pigments in them. You can't tell the
difference in these pigments by looking, even if
you could see inside a person's eye.
Why do you think that animals that hunt at
night are usually colorblind?
