Question

Colour of clear sky is blue

Answer 1

sky seems to be blue as the rest of the colours in the visible spectrum gets scattered due to their low wavelength..

Answer 2

A clear cloudless day-time sky is blue because molecules in the air scatter blue 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 blue light has been scattered out and away from the line of sight.
