mantis shrimps have SIXTEEN types of colour-receptive cone cells and are able to see both UV and polarised light.
I remember someone saying that this makes them see everything in a tye-die like pattern of colors, but I have no idea where I read that anymore or if it's true.
I saw somewhere that tigers are orange because a lot of their prey is reg green colorblind, so to a deer they’re perfectly camouflaged, but enough deer are not color blind that it isn’t an extinction level threat. Maybe this allows them to predate or avoid predation more easily? Maybe it’s now not required because those predators are no longer present, but is evolutionary inertia.
Because they can't see shades between colors, their brain doesn't have the capacity to mix colors. So they have all those cone types so that they can process visual information in the eye rather than waiting on potato brain to catch up to what the eyes see
