Description:
Thanks to digital photography and a particular processing technique, it is possible to emphasize the soft and imperceptible colors of the lunar surface. Digital images of the Moon contain a lot of information that can be easily extracted with image processing software. The color tones visible in the processed images of the Moon are mainly due to two minerals: iron and titanium. Basalt plains (dark lunar regions called "seas"), which contain relatively large amounts of iron oxide (FeO) appear an orange-brown color, while seas which contain large amounts of titanium oxide (TiO2) in addition to iron oxide, show blue color hue. The lunar highlands, geologically ancient and highly cratered regions, on the other hand, have a low iron and titanium content, reflect sunlight well (high albedo) and in this elaboration appear yellow-ochre in color. Young impact craters such as Tycho and Stevinus exhibit white-blue rays of ejecta (ejected material).
