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.

The color of sky is due to the property of dispersion of light
the white light of the colour before reaching the earths surface gets dispersed into its 7 components VIBGYOR
the molecules present in the atmosphere are capable of scattering only the light with shortest wavelength and hence red light wont get scattered
As the light that we get from sun is white in color and due to atmospheric refraction splitting up of white light takes place and the light with longest wavelength gets lost in the space and blue and violet has shortest wavelength but the intensity of blue will be much more than that of violet which makes us see the sky blue in colour
