  You thought the moon was black and white? The human eye can not discern
the colors on this star, but by forcing on saturation, these exist well! The colors give
informations on the geology of the surface of the moon. Moreover, in the many
impact craters we can observe the composition of the deeper materials while the
materials scattered by the impact of meteors are different in composition
from that of the material at the surface.
