Very informative. But remember the human is just the observer of all phenomena or stimuli that is occurring in the universe and your statements like this one concerning rods:

“However, they do not distinguish between colors, and have low visual acuity (measure
of detail). This is why the darker conditions become, the less color objects seem to
have.”

bothers me slightly because it implies the human (specifically the rods) is doing the action while the truth is the human is just observing the universe. What I mean is this:

The reason we see any object in color is because the object is absorbing certain wavelengths of the visible spectrum (light) and reflecting certain wavelengths of the visible spectrum (light). Your correct in your description of how the rods and cones work when they are stimulated by light but I propose to you: isn’t it because there is very little light hitting the object and therefore very little light reflecting off the object that it appears to not have much color and not effect or defect of the rods??? An “imagined” “perfect” eye-brain system wouldn’t see much color any more than the human eye-brain system would.

In short…no light…no color

I forgot to add…your article was impressive and very informative. I didn’t mean to make light of it. It was more of a philosophical question and I feel your article had a certain tone of human-centrism when we are just a part of the universe, not the center of it.
