To be clear, this is not a rejection of the theory, because your brain does a lot of magic to make color (or even object) perception "stick" as things move in and out of peripheral vision. See for example:

- Someone 3y agoYes, but not to the extent this theory would predict. If “the brain assumes that spatial frequencies coincident with the cell spacing are most probably because the object is that color, not because the object is weirdly striped as black and white in exactly the same pattern as the retina”, an object perceived as red from 4 meters away would be perceived as purple from 2 meters away (or vice versa), and as yellow from 3 meters distance (the visible light spectrum roughly is from 400nm to 800nm) And that would apply to all objects.
- IIAOPSW 3y agoNo it wouldn't. An actually red object would have the exact same red-cone spatial pattern no matter how far away it is, because the pattern is coming from inside the retina not from the object itself. An actually weirdly striped black and white object with the exact same pattern as the retina would behave like you said.
