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 variations of the surface not easily identified in a single band image. Today's false color image shows part of Margaritifer Terra. Dark blue in this band configuration often equates with sand or basaltic materials.
