Answer 1

Initially all you need to do is to be slightly closer in colouration and shape to hide from predators and increase your chances of survival. When all the obvious creatures are removed from the gene pool pressure is then on the remaining ones and as new mutations occur those which enable a greater degree of hiding survive and those that don’t become lunch, the process takes thousands or even millions of years before the current forms are so well hidden. Camouflage can also happen in plants as well as animals. https://youtu.be/9rOURRXEbk0
