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 Daedalia Planum. The pale blue surfaces are thought to be early morning ground frost. This image was collected during the winter season.
