Why we feel sky blue in color?

 The blue color of the sky is because of Rayleigh scattering. As light moves by the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air. Though, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in dissimilar directions. It gets scattered all around the sky.

Whichever direction you look, some of this scattered blue light reaches you.

As you see the blue light from everywhere overhead, the sky looks blue.
