Look at it! Depending on the situation, it may look completely black (cloudy, moonless night), black but with visible stars (no clouds), bright, sort of white (near a city), dark blue (moonlit night), ...
Since the moon has no atmosphere, the day time sky looks like the night time sky, only our sun looks like a REALLY CLOSE AND BIG star.
The color of the sky on the Moon is black, always, day or night doesn't matter.
Actually, the sky looks blue. But to some animals it might look gray. So how does anybody really know what color everything is? They don't. They're not sure.
None ! A pig can't look up.
As you may know, when you mix the colors yellow and green, you get the color blue. The yellow from the sun reflects off of the green ground, making the sky look blue. At night, when there is no sun, you see that the sky isn't blue anymore. This is actually what the sky looks like all the time. The blue color is just an optical illusion. It is quite amazing though.
Mars
Starry night looks like a town with a big pointy mountain. In the sky, there is the night sky with stars and a moon in a swirl.
