If there were no atmosphere at all, the sky would be black. If there were some other kind of atmosphere, the sky would be colored according to the make-up of the atmosphere.
Pluto is not a planet anymore, but the sky would be black
I dont know really but I think it would be black
The color of the sky on earth would still appear blue but the "sky" around you would be black
On the moon the sky will look blue.

Mars's sky would be close to black, as there is no atmosphere that could add color.
The blue of Earth's sky is caused by sunlight scattered in the atmosphere. When you get above the atmosphere, the sky turns black. The Moon has no atmosphere at all, and so the sky looks black at any altitude.
There would be no life.
