The THEMIS VIS camera contains 5 filters. The data from different filters can be combined in multiple ways to create a false color image. These false color images may reveal subtle variations of the surface not easily identified in a single band image. Today's false color image shows part of the margin of Chryse Planitia. Dark blue in this false color combination is mostly likely basaltic material/dunes.
