Light is a kind of energy that can travel through space. Light from the sun or a light bulb looks white, but it is really a mixture of many colors. The colors in white light are red, orange, yellow, green, blue and violet. You can see these colors when you look at a rainbow in the sky.
The sky is filled with air. Air is a mixture of tiny gas molecules and small bits of solid stuff, like dust.
As sunlight goes through the air, it bumps into the molecules and dust. When light hits a gas molecule, it may bounce off in a different direction. Some colors of light, like red and orange, pass straight through the air. But most of the blue light bounces off in all directions. In this way, the blue light gets scattered all around the sky.
When you look up, some of this blue light reaches your eyes from all over the sky. Since you see blue light from everywhere overhead, the sky looks BLUE.
(During my school days my geography teacher gave a lecture on sky is blue becuz our planet has Ocean which looks blue in colour and that reflection of colour makes the sky look BLUE)

The sky is blue because of the contents of the air in the atmosphere, such as hydrogen and oxygen. The light we see from the sun is made up of many wave lengths, among these is the blue spectrum or wavelength of light, its the only one of the wave lengths that gets diffused and bounced off of all of those particles in the atmosphere the most, so we see more of it in the sky. Nothing to do with dirt particles in the sky, or the reflection of the oceans against the darkness of space. It's all about light spectrums and the wavelengths being broken down.

In-fact, sky is doesn't have any color(Sky is nothing but the space you are looking into.....just like a dark room). Its only because of dust particles and other impurities, the color BLUE( one amongst the VIBGYOR) gets scattered all over. Thus the sky appears to be Blue in color. Close your eyes.....that's the actual color of the Sky :)!

When light travels in space, it does not reflect in space as no one knows what is the height of sky, so the light get staggered in space forming blue color, the space is dark black with white light staggered in space looks like blue actually no one know where is the sky and what is its color

The sky is not blue it has no colour, it is the dirt particles in that air that makes it look blue, just like the sea.
If you don't believe me, do what 38c suggested. Ask Jeeves.

Because Avogadro's number is 6 times 10 to the twenty-third power.

actually the truth is that there is no sky but it looks blue to us bcoz of some light effects

coz blue has small wavelength,therefore large scattering!
(rayleigh law of scaterring says intensity is inversely proportional to wavelength)
also 3/4 th of earthis water so blue color is reflected and thats the color of sky!

Due to O3 (Ozone gas) The Color of ozone gas is Blue when it goes thick

Frequency of blue color in spectrum of light is more.. due to atmosphere of earth
