Color image of the Caloris basin and adjacent regions. Orange hues just inside the Caloris basin rim mark the locations of the kidney-shaped depression and related features. The craters on the floor of the basin show several different colors on their rims, indicating different depths of excavation, and some have been embayed, suggesting post-impact volcanic activity. Statistical methods were used to isolate and enhance subtle color differences using data from the multi-band multispectral images obtained by the Mercury Dual Imaging System instrument.
