The Mast Camera (Mastcam) on NASA's Mars rover Curiosity showed researchers interesting color and patterns in this unnamed rock imaged during the 27th Martian day, or sol, of the rover's work on Mars (Sept. 2, 2012).

This image of terrain inside Mars' Gale Crater and the inset of the calibration target for the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate how false color can be used to make differences more evident in the materials in the scene.

This image of terrain inside Mars' Gale Crater and the inset of the calibration target for the Mast Camera (Mastcam) on NASA's Mars rover Curiosity illustrate how the calibration target aids researchers in adjusting images to estimate "natural" color, or approximately what the colors would look like if we were to view the scene ourselves on Mars, using the known colors of materials on the target.
