Has it existed through different colours in its evolution to find the best one?

I suppose as far as selection is concerned, colour is in the eye of the beholder.
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?

There are animals which are green in colour. 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.

Thanks. 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:
