These experiments highlight just how much processing our brain does to give the appearance of what we observe compared to the raw sensory input from our rods and cones.

Yes, I wonder how much of this is biological vs a learned prior.

It's amazing to think about how many optical illusions our brain can be tricked into due to this perception of color through biological responses. And somewhat of a paradox: our brains are the ones that come up with these optical illusions, but can't correct it themselves.

I think it is fascinating how the human brain is unable to process sensory information in isolation, but needs context to create a meaningful perception. There's always a comparison being made here, like "this colour is darker/brighter than this other colour." This isn't just limited to colour or sight, either—see the missing fundamental illusion or size-weight illusion. It just goes to show that our brain works by making comparisons to previous information.
