A clear cloudless day-time sky is bluebecause molecules in the air scatterblue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the bluelight has been scattered out and away from the line of sight.

The true answer isn’t very complicated. There is no sky. The sky is an illusory surface. “The sky” isn’t colored blue, since, that blue surface up there? It doesn’t actually exist.
Think about it. During overcast days, is our sky colored gray? …Or is it really just the clouds which are gray? And during bright morning fog, is “the sky” white? Or are we just seeing the morning sun shining on white fog? OK then, whenever there’s no fog and no clouds, what up there is colored blue?
Air is blue.
A thick layer of air is a blue-colored substance. And the only thing up there is the air.
When we look upwards, we’re seeing air, we’re looking at brightly-sunlit nitrogen and oxygen. There’s nothing up there but bright blue air, seen against the black of outer space. (Air isn’t perfectly transparent as everyone thinks.) When light shines on air from the side, air is colored bright blue.
