What is the real colour of the sky?

I am not really sure,but i would be more than glad if its blue because its my favourite color.If given a chance,which color you would want it to be..?

Hi ?????, I am not referring to anything now, just saying from my though - it is light blue. As we think, it is the mix of all atmospheric particles formed and when it extends to a the large thick wide area, it turns into bluish and and keep changing due to different phenominon happening around. Hope you have referred somewhere and share it here for everyone's knowledge update. Regards

The sky in itself doesn't have any colour. It is the colour of light emitted from the sun that we observe in the sky. At night, there is no illumination from the sun and so the sky looks black at night. But during day time if the atmosphere is clear the sky appears to be blue and it is due to Rayleigh scattering of light. As light moves through the atmosphere, it hits the gas molecules which are much smaller than the wavelengths of the different colours of light. The subsequent result depends on the wavelengths of the different colours present in the light. Most of the longer wavelength lights comprising of red, orange & yellow light are affected little & pass through the gas molecules. But the shorter wavelength lights like the blue are mostly absorbed but very soon the absorbed light is given off by the gas molecules. The given off blue light is then radiated in all the directions & gets scattered all around the sky. As a result, some of this scattered blue light always enters the eye in which ever direction the eye is fixed towards the sky & so the sky looks blue. The molecules of oxygen & nitrogen in the atmosphere are mainly responsible for this scattering of light which occurs as the electromagnetic field of the light waves induces electric dipole moments in the said molecules. Rayleigh scattering of light can also occur when light travels in transparent solids & liquids but is most prominent in gases.

well, literally based on what i saw, it has different colors depend on the weather. when the sun shines, the color of it is blue and there is white puffs like cotton in it as well. if we have a bad weather, the color of it is gray, maybe because of the water that will landfall. sometimes, too, it has a blackish color as well more if there is a storm. :) hehe

The real color of it would be black, because without the reflection of light in to the earth it wouldn't be blue.

The sky itself has no colour of its own but it looks blue in a clear atmosphere due to Rayleigh scattering of light.

The sky appears blue because short wavelengths (the blue end of the spectrum) are absorbed and scattered whereas longer wavelengths are more inclined to pass straight through. This means that, wherever you look (when there are no clouds), you see the scattered light which is blue. See this explanation: http://www.sciencemadesimple.com/sky_blue.html Only actual light sources can have 'real' colour. The colour of everything else depends on exactly how it reflects/transmits and absorbs the different wavelengths contained in white light.

Hi, What an coincidence? Yesterday I was looking outside the widow and thinking that what was the real color of the sky? It looks blue. What is the reason behaind this blue color? So I don't know the answer. I am also finding the answer. Thank you for posting this discussion.

Didn't we learn this in science class........ black is the absense of light and certain colours are the colour that reflects. White reflects all colours
