@glacial Outstanding link. Thanks. You may have posted it before, but this it the first time I’ve seen it.
@DWW25921 There were no new colors in @glacial‘s link, but then I’m looking at the photos with human eyes that can only see the 3 primary colors and mixtures of them.
@PhiNotPi It sure would be interesting to jack into such a brain and be able to see what its eyes are taking in. BTW, there is a human mutation currently only found in a few women that adds a 4th type of cone receptor to the eye. Compared to them, the rest of us are all partially color blind. But pigeons have 5 sets of color receptors. They must see a very interesting world.
@JLeslie Unfortunately, there is no external technology that can let us see colors for which we have no receptors in our eyes. Even if we were somehow able to jack a pigeon’s eyes into our brains, our brains haven’t ever learned to decode those signals. Unless it was done from infancy on, we probably wouldn’t be able to see any colors we don’t already see. And besides, where would we put them on the color wheel? It’s already full. :-)
@KNOWITALL Birds have some incredible vision. No question birds see differently.
@gailcalled Did the evil nurse relent and give you more pain meds? I don’t think @KNOWITALL mentioned flowers. :-)
