A statistical comparison between the lunar surface and the earths rocks and materials with respect to color and luminosity was carried out in an article based on published materials. It was established that a simultaneous similarity for the distribution curves according to brightness and color between the moon on the one hand and the earths rocks and meteorites on the other was not obtained. The various assumptions introduced in order to explain the color characteristics of the lunar surface are discussed. The most reliable is the hypothesis according to which the lunar surface is covered by a porous vesicular slag formed from bedrock under the action of explosions accompanying the meteorite impacts.
