How can a tiger ‘know’ that it’s prey sees it as a different colour?
Has it existed through different colours in its evolution to find the best one? https://themindunleashed.com/2019/05/tig...green.html
Oh my God, I hate all this.

But I don't understand why the article says orange is "the perfect choice" for tigers because their prey are red-green colour-blind. I can see why the colour-blindness could make it one of a range of possible colours for camouflage, but shouldn't there be another reason why tigers are orange rather than green?

But it doesn't seem common within the range of colours for hair or fur. I have seen people with green and blue hair, but I'm not sure that evolution was responsible.

After I posted, I wondered whether I was just showing my ignorance by imagining a tiger could be green. But a quick Google search suggests the reason why animals tend not to be green isn't entirely understood: https://biology.stackexchange.com/questi...ot-a-thing
