The blue color of the sky is due to Rayleigh scattering. As light moves through the atmosphere, most of the longer wavelengths pass straight through. Little of the red, orange and yellow light is affected by the air.
However, much of the shorter wavelength light is absorbed by the gas molecules. The absorbed blue light is then radiated in different directions. It gets scattered all around the sky. Whichever direction you look, some of this scattered blue light reaches you. Since you see the blue light from everywhere overhead, the sky looks blue.
As you look closer to the horizon, the sky appears much paler in color. To reach you, the scattered blue light must pass through more air. Some of it gets scattered away again in other directions. Less blue light reaches your eyes. The color of the sky near the horizon appears paler or white.

Because the dust suspended in the atmosphere scatters the light from the sun. The sun's yellow-white light is made up of a spectrum of visible colors, from red to deep blue-violet; the dust reflects and disperses the red end of the spectrum, leaving only the blue component behind.
When the sun is low in the sky, it's just the opposite: the dust in the atmosphere absorbs all the blue; only the red can get tghrough, which is why sunsets and dawns are so often red-pink.
