It's whatever

It turns out a lot of animals can’t see the difference between orange and green!  Elephants, for instance, have dichromatic vision (two types of cones, rather than three like most humans.) 

It doesn’t matter what zebras see, because tigers are not native to Africa and do not naturally hunt zebra.  Tigers are Asian and mostly hunt animals like deer, elk, and buffalo.  These aren’t animals with great color vision.  They don’t need to have it because they don’t eat fruit and so don’t need to know when the berry is ripe vs when it’s not.  Good color vision is too expensive to have if you don’t need it.  Deer put their vision stats in a wide field of vision that is sensitive to motion, low light capabilities, and possibly seeing UV light.  They don’t have great color and lack a lot of acuity, but have a great sense of smell and good hearing.  That’s way more useful if you’re prey.  Deer see well in the blue end of the color spectrum and less well in the red.  This makes sense because deer are most active in the dawn and dusk periods, when there is more blue in the light.  Tigers are taking advantage of deer eyesight by being orange.

Ok but like, I think you underestimate just how well they blend in when actually in the environment. Like, just using tigers as an example.

Are you, sure about that?
