For years I’ve tried to understand why colours can produce a profound sense of depth. The stereo experts have no explanation at all, they’re very stuck in their ideas about stereo all being two images combined ‘by the brain’. I think that’s nonsense. Only one image here and the ‘depth’ is right at ya. It’s actually a known phenomenon. Called chromostereopsis. But they still have no idea why it works, because they keep using the same ‘binocular disparity’ ideas to explain depth perception.
