Well the difference in color comes from different types of rocks that lay on the surface of the moon. The darker areas are from ancient beds of lava, that formed while the moon still had a liquid core. A big asteroid hit and punch a hole in the outer shell and the crater filled with lava. There are also brighter area's of the moon like the lines heading away from some of the larger craters, these are little glass beads sitting on the lunar surface, after an impact from an asteroid there was enough heat generated to melt the silicate rocks on the surface of the moon, and the debri cooled quick after impact as is was being ejected by the impact site. Because it was cooled before it landed on the surface they formed little spheres of glass strung out of the impact site, these reflect light very well so they appear brighter. Most of the rest of the moon is covered with dust from billions of years of meteroids coliding with the surface, because there is no erosion on the moon and no wind and no atmosphere, the dust just sits were it landed, and is never moved away.

Most of the soil, gravel and rock on the moon is gray.

Because it's covered with rock and dust that is grey.
