High level color perception is one among unique to human species why this deferential selection happen to human being is subject to study. This thought always trigger if we passes our eyes through horizon where we can experience the colorful display.

Just watch this photo you can see even mountain merges with sky by diffusing the color
If we suppose we look from a spheres. Is it a chromatic adaptation happens to our vision?
My question is any environmental, existential or survival reason for this evolutionary uniqueness to human species? –High-level color separation
