Color constancy, if I understand correctly, is a product of some of our cells in our visual cortex applying a type of color processing algorithm to what we see, allowing us to distinguish the color of an object in various light conditions (e.g an orange is orange at night and during the day).
Of course that means our brain is lying to us, giving us a false impression of what we are actually seeing. This optical illusion illustrates the damnable liar our brain can be:
(both square A and B are actually identical to one another, despite what your pants on fire brain is telling you).
This brings to mind a couple of questions:
First, what would we actually see if these math genius cells responsible for calculating the color we actually perceive were not there, or where damaged? Is there any medical condition that could result in this phenomena? Is there some way to simulate what a green apple ACTUALLY looks like in different lighting - trick these cells somehow?
Could we re purpose these suckers so that I might ace my next math exam, or at least get really good at Photoshop?
More seriously, are there any other ways our brain lies to us? And are there metaphors or examples of the contrast between reality and what is perceived for these other “lies”?
