The tiger’s coat appears garish only to human eyes.

The perception of colors comes from photoreceptor cells called cones. There are different types of them and each captures a specific color. Primates have three types of cones: one for blue, one for red, and one for green.

But they are an exception in the animal world, because the vast majority of mammals have only two: those for blue and for green.

Although the tiger appears orange to us, it can therefore blend into the eyes of most animals even amidst the greenest vegetation.
