The blue colour of sky is due to the scattering of light by small particles of the atmosphere (air molecules) when the light is incident on particles whose size is smaller than the wavelength of light, it is scattered. According to Rayleigh law, the intensity of scattered light is inversely proportional to the fourth power of wavelength. As the wavelength of blue colour is smallest and that of red light is longest, the blue light is scattered most and the red light is scattered least. The scattered blue light reaching the eye gives the appearance of a blue sky. The sky will appear black in the absence of earths atmosphere because no scattering of any colour takes place in that case. While flying in an aeroplane one can observe the sky to be black at high altitudes.

Sky is not blue it just looks to be so for the people who lives on the earth..........as earth has got atmospherical particles which scatter the light which leads to its blue color which gets more scattered..... hence its blue color even during day time if go out of the earth's atmosphere it will be dark in color............:-)

Sky colour is blue Because there are certain light and molecules which produce Blue colour. So it seems like Blue colour. But actually it's not Blue.

It is blue as caused by sunlight off the molecules of the atmosphere. Blue has short wavelength and thus sky appears blue.
