Why sky appears blue?

A sunlight consists of 7 different colors. In short its colors are called as VIBGYOR, Violet, Indigo, Blue, Green, Yellow, Orange and Red. These are also the colors of Rainbow. In day time when the sky is clear molecules in the air scatter blue light from the sun more than they scatter Violet, Indigo, Green, Yellow, Orange and Red.

Similarly when we look towards the sun at sunrise and sunset we see red and orange colors this is because the blue light has been scattered out and away from the line of sight and only red and orange colors are scattered from the sun more than they scatter Violet, Indigo, Blue, Green and Yellow.
