the brain’s actually trying to understand what things are made of, and it’s guessing at that based on the light that enteres the eye.
this is why when you pick up a thing outside and take it inside, it doesnt change color (edge cases exist), even though the light that reflects off of it into your eye absolutely changes a lot.
Technically, all the colors are fake. They’re just the halucinations of a brain trying to understand the input from sensory organs.
