Many Fantastic Colors

February 25, 2011
The IRB color image here shows diverse colors. These are infrared-shifted colors, which reveal color distinctions when minerals like olivine are present. Olivine is greenish in natural color but appears blue in the IRB color.

Other rock types are also present, giving the mosaic of colors. This image covers a knob in the Argyre impact structure; HiRISE acquired this image as a "ridealong" to a CRISM target.
