Mars does not wear its nickname for nothing: in telescopic photographs or images of probes, our neighboring planet appears in strong orange-red because of the large amount of oxidized iron. Also in this picture is a part of the Martian surface to see, however in false colors. Now, not the NASA staff have a general dislike for the color red, but rather serves a scientific purpose.

The colors, which were subsequently generated with a special visualization technique, show the different materials of the surface. So the typical Martian soil suddenly appears greenish-gray. Pink spots are made of blown dust, purple indicates olivine-containing basalt. The bright blue of the central elevation, Mount Sharp, probably indicates only minerals present there.

The image showing the Gale crater was taken by the THEMIS camera of the Mars Odyssey probe.
