What is the colour of Sky

I've seen this discussion before, and know the answer, so would you really like to know? The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue. As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white. I hope this answers your question. Brightest Blessings. :-)

It is because of the scattering of light by the air molecules. You can read about the Raman Effect in wikipedia. http://en.wikipedia.org/wiki/Raman_scattering

I do not know surely you wish correct answer or only joke. if which you wish erudite answer why chromatic sky is blue...i am do not know surely his answer. but if that is joke, my answer is ....if that colour of sky is brown, everybody needn't busy again to celebrate days of valentine. because enough by just sky approach is he/she have satisfied.

i seen another discussion like this but they was saying black lol. heres a couple of sites you might find interesting:): http://www.sciencemadesimple.com/sky_blue.html http://math.ucr.edu/home/baez/physics/General/BlueSky/blue_sky.html

sky have no color :P it the see look blue
