The sky is blue because oxygen in the earth's atmoshpere scatter blue light. This scattered light then comes to us on the surface from many different directions. It is for the same reason that the sun appears orange or red during sunsets. because the sun's light has to travel though more atmoshpere at those times to reach us, more of the blue light from it is scattered, leaving the sun looking red.

Depends on the mix of light that passes through it and the subjective way the observers eye 'sees' it and the point of view - altitude and angle of view, and what is currently in the sky - vapours, pollutants etc.
It can be deep blue, black, grey, orange, blood red, sickly yellow, pale yellow, white, grey, even green, purple, I have once seen it (and all the reflections at ground level) a strong and bizzare yellowy mauve whilst driving from Birmingham to Bournemouth - for the enitire journey.

If it is seen from the earth, the sky is blue in the mornings and afternoon and coloured (orange/ blue/ white) in the evenings or by the time of sunset!!..
If you go out from our atmosphere, the sky is Black..!!

Cerulean.
This color is due to light from the Sun, which is Rayleigh-scattered by molecules in the atmosphere (not primarily ozone, however). Since this scattering cross-section is proportional to wavelength to the -4 power, blue is scattered much more effectively than longer wavelengths and the result is blue, with a little green and almost no orange or red.

the colour seems blue because of the gases in the ozone layer - they filter the light in such a way to make the sky look blue...

mine is light blue, with no clouds on it.
but actually, that is only the sun light being filtered through the atmosphere. in reality, the sky is nothing but space and doesn't have any colour.

It all depends on the angle at which the light of the sun hits our atmosphere. Considering the suns light can be broken into the color spectrum of Red, Orange, Yellow, Green, Blue, Indigo, Violet, I would assume in theory it could be any of these colors.

The colour of the sky is the ozone layer around us which is why it is blue. Or something like that.
Ozone is made up of three oxygen molecules whereas oxygen is normally 2 molecules

If you go up high enough it's BLACK.
It only becomes blue or red when viewed from lower altitudes due to light being reflected and refracted by dust and other impurities in the atmosphere.
