How do animals develop camouflage, when they don’t know what other animals see?

Question

I’ve always admired the patterns of tigers, leopards, mantis shrimp, butterflies, etc. But I’ve always wondered how and why they become like that.

Answer 1

It’s natural selection, the luck of the draw. As more and more generations are born, there are tiny random variations in patterns. The animals whos patterns worked best would have more success and thus reproduce more. Over time this would continue until an optimal pattern arose and dominated.
