It is the absence of light. Plain and simple. Light needs a source or something to reflect off of between the source and your eye. You can see planets because the source's (a star) light is reflecting off of the planet.
Actually, the sky is blue not because that's the color of the sky, but rather because of a scattering effect. Colors are lightwaves of varying length. Shorter wavelength light (blue) is absorbed by the gas molecules in our atmosphere.
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. (http://www.sciencemadesimple.com/sky_blue.html)

We see blue sky in day because the spectrum of visible light is split from red (shortest wavelength) to Violet (longest wavelenght)
by the atmosphere of the earth. The blue hue is the last color scattered as the remaining colors are transmitted.
At night we see black when all the light not light is reflected or scattered. Only when the light is reflected to we see color like from the planets or stars.

The black is outer space. At night there is no light to make the blue visible. The blue is the color we see best, but if there is no light we see black as at night, while the stars and moon are either giving their own light, or reflecting the sun's(the moon)and so we can see them.

Ii is also the blue cloud that is present this happen as a result of the rotation of the earth in which the reflection of the sun to the earth was hinder by the moon.
