What realy is the color of the sky and why?

Color is all relative ain't it, if you say its not blue either you live in a polluted city or I'm insane

reen is funny, the sky is still blue in the middle of a desert 100 of miles from the water, the Gas Oxygen and nitrogen make the color blue, actually more Nitrogen which is greenish and Oxygen which is light blue

Actually, the coloring in the sky that you observe is a result of light rays being scattered by air and anything in it. The rays of light with the longer wavelengths, such as reds and yellows, tend to travel more easily through the atmosphere, while the rays with the shorter wavelengths, like blues and indigos, tend to be dispersed more easily. These more easily dispersed shorter light rays are what give the sky its blue color.

The color emitted by the refraction of gasses in the atmosphere is what causes the sky to be the color it appears. The protective ozone layer which is thicker in some places than it is in others, reflects blue when exposed to the suns radiation. So ozone gas expressed as O3 is responsible in large part to the blue sky. The dust particles mentioned in the previous paragraph are responsible for the various hues and colors we see such as the red sunsets.

As a result we see it as blue.

Well really the sky is said to be clear, but because of the reflection on the rivers and oceans we see it as blue.
