If you were to observe the sunset on the Moon, would you see the space around the sun as red, like you do on earth? Yes, because the color of light is independent of where you are. No, you would see it blue because of scattering of light. It would depend on the time of the day when you look at the sky. You would not because there is no atmosphere on the moon to scatter the light. You would not because the moon absorbs all the colors of light. You would see it black because the moon reflects all the colors. Yes, you would see it red like on the earth because both the moon and the earth are spehrical.
