sees. There are two different kinds of color
(called "pigment")involved and they are in two
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
