I was wondering at what stage of our perceiving of light is the color processed? I know that it is the rods responsible for interpreting colors, and I
was thinking about this idea that we all perceive the same colors as being different, which leads me to: is it the rods or the brain that would be
responsible for these differentiations?
The reason I ask is because of Jerry Orbach. The actor, recently deceased, donated his eyes to the medical community, and each one was given to a
different person that already had one functioning eye. If his rods and cones were different than those of the people his eyes were going to, what must
that be like for them? Do they see two sets of color and light data that are somehow jumbled together in their brain? At the very least, we know from
a previous reply that there are different levels at which we can perceive color differences, so would these two people have two different versions of
gradations in their head? What if they look at a red sign with one eye, then close that eye and open the other, only to see something that is made up
of a variety of reds and oranges? And maybe those people, when they open that other eye, see green instead of the red they are accustomed to on that
Of course, it's likely that the eye has far less to do with it than the brain, in which case nothing has changed for them. I think that would be
rather sad. The opportunity to experience the world for the first time lost because of a stupid brain.
Also, I don't remember the exact details of what I'm about to reference, but I once saw a show on the discovery channel about creatures that live in
marshes, and they spoke of a particular kind of shrimp thats eyes are so advanced, it absorbs sixteen different wavelengths of light instead of just
the boring three. This thing must be able to differentiate billions and billions of different shades. Again, wasted on a stupid brain.
