Answer: The sky is the layer of atmosphere under which we live, It is made up of several colorless gases. The gasses interact with the light coming from the sun to give the impression of colour.
A bit of background: The white light from the sun is a mixture of all colours of the spectrum. Each colour of light ahas a wavelengths. The visible part of the spectrum ranges from red light (wavelength =720 nm), to violet (wavelength =380 nm), with orange, yellow, green, blue and indigo between. The human eye reacts most strongly to strongly to red, green and blue wavelengths. This gives us colour vision. The explanation: Light passing through a clear fluid with suspended particles is scattered. Some wavelengths like blue are scattered more strongly. The first person to notice this and experiment with it was John Tyndall in 1859. So he got to mane the effect the Tyndall Effect. He made three important observations: * From the side, (the way we see most of the sunlight in the sky) the beam can be seen by the blue light it scatters * The light seen directly at the end (looking towards the source) is red. This is the way we see the sunlight at sunset
* The scattered light is polarized. This is why polarized sun glasses make some parts of the sky seem darker.
Some early researchers (Tyndall and Rayleigh) thought that the blue colour of the sky must be due to small particles of dust and droplets of water vapour in the sky. Later scientist discounted this and proposed that oxygen and nitrogen molecules are the cause of the scattering.
In 1911 Einstein did the math to prove that the molecules could cause the scattering. Technically the molecules scatter light because the electromagnetic field of the light waves induces electric dipole moments in the O2 and N2 molecules,

Is the sky blue a hypothesis?
No. The sky is just as blue as a blue shirt though. Technically an object, such as a shirt or the sky, is not blue. The object just appears to be blue because it absorbs all other colors of the spectrum and reflects blue back which is the same with any other color seen.
Why is the sky and water blue?
The sky is blue because of Rayleigh scattering -- blue photons scatter off air molecules to a large extent, while the other colors travel directly in straight lines from the sun, making the sky appear blue and the sun appear yellow (white minus blue). In space, or on the airless moon, the sky is black and sun is white. It is NOT true that oceans look blue due to sky reflection. Water also scatters blue light, so the explanation of its color is largely the same as that for the sky.
The sky's blue color is caused by?
The sky's blue color is caused by the refraction of light in the water vapor in the air, and blue is simply the color we see most.

When are the gases in the sky blue?
Gases in the sky are not blue, the blue of the sky is caused by light scattering. However, oxygen is blue if you liquefy it.

What does sky blu look like?
The color sky blue is a lighter shade of blue. The color is called sky blue because it is to resemble to same color as the sky. When the sun is out the sky is a beautiful shade of blue.
