One of the most colorful images taken of the Moon, this NASA compilation shows shades of green and brown in addition to gray. Many Moon photos are actually color images! Unfortunately, unlike the planets, the Moon's surface has no brightly colored areas. Most of its color is a mix of dark browns, grays, or black.

Is it multiple choice?
