It's not blue. It's actually gray. Dark in fact. If it were a light gray, it would shine with half the sun light on a full moon night. Blue Moon is also an expression for having two full moons in a single month. I don't know where the word 'blue' came from tho.

After forest fires or volcanic eruptions, the Moon can appear to take on a bluish or even lavender hue. Soot and ash particles, deposited high in the Earth's atmosphere can sometimes make the Moon appear bluish. Smoke from widespread forest fire activity in western Canada created a blue Moon across eastern North America in late September 1950. In the aftermath of the massive eruption of Mount Pinatubo in the Philippines in June 1991 there were reports of blue moons (and even blue Suns) worldwide.

In a map of the moon that shows hydrogen or mineral content, the moon could appear blue, or even in maps showing thermal variations on it's surface. However, from the surface of Earth, the moon appears a light grey color, and the regolith that coats the moons surface is also grey. The color variations on our natural satellite, therefore, are mostly different shades of grey.
