For predators that hunt from ambush, it is important to remain invisible until the decisive throw. But for some reason, tigers are not only orange, but also striped.
An article explaining this feature was published in Live Science. The color orange is very visible to humans, so it is used for items that need to be visible, such as life jackets or traffic cones. This is because humans have tricolor vision. Our visual receptors perfectly distinguish 3 colors - green, red and blue - and their combinations. Monkeys have similar vision.
But many land animals have dichromatic vision, meaning they can only distinguish between blue and green, like humans who suffer from color blindness. Cats, horses, dogs, and deer see this way. The main prey of tigers, the deer sees it in green, not orange. This makes him invisible in the grass or bushes. If it were green, it would be even more inconspicuous, but nature lacks the ingredients for green fur.
Experts emphasize that it is easier for nature to obtain orange or brown color due to the biomolecular structure of the structure of the animal. There are no animals with green fur in nature, except the sloth, which has a green color because of the green algae living in its fur.
