Solar eclipses on the Moon the surface appears not just black but red and brown (according to the Danjon scale) because the only sunlight available is refracted through the Earth's atmosphere on the edges of the Earth forming an atmospheric ring as it is shown in the sky in a painting by Lucien Rudaux. During eclipses with long totality, temperatures plunges but not in many parts of its mares especially Oceanus Procellarum and Mare Tranquillitatis, and mid to large craters (especially with basalt floor) mostly in the middle portion of the Moon, some young craters and a few distant large craters, notably Tycho (being located
