Do we see bands of color in a rainbow because of the physiology of eyes or the way the brain interprets the frequencies? or are those bands of separate colors a product of unequal refraction?

I’m not sure I understand your question. None of the options you have listed are mutually exclusive so the answer is “yes to all”
Color is a subjective experience that our brains form. But our eyes are the mechanism that picks it up in the first place. Within our eyes we have cells that each reactive to different frequencies of light (specifically, red, blue, or green). Those cells then send a signal to the brain. The brain goes “alright a bunch of cells that pick up red are telling me they picked up something, I’m gonna say we are looking at something red”
If either our eyes or our brains function differently we would almost certainly see something entirely different than what we normally see. They are both important.
Infact, color blindness is caused by not having the correct cells in your eyes. And I’m sure there are people that have fully functional eyes but some kind of brain damage that changes their vision.
