Why is it that the color of the sky is blue?

becoz it is blue that's why it look blue. just joking . ur answer is . 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 (mostly Nitrogen). 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. have a nice day.

I think you have a point my friend. Maybe because of the chemicals that can be found in the sky and so if the sun will strike those chemicals, i will be look like blue. Or maybe, it is because of the Ozone Layer that are in our athmosphere. The atmosphere that covers our earth in order for sun not to strike directly to the earth so that the earth will receive not too much heat. I think that is my idea that coencides also with your idea.
