Atget in Color
Though Mercury is not known for having an especially colorful surface, some regions show a strong local contrast in color. Like other craters in Caloris, the interior and ejecta of Atget are darker and bluer than the typical brown volcanic plains. These craters help scientists to get a look at the three-dimensional compositional variations with the Caloris basin, and provide a way to judge the thickness of the volcanic plains (over 2 km here!).
