This is a false color image of the sun dial on the Opportunity Rover from Sol 2929 captured on April 21, 2012. If you noticed, at the edge of each of the corners of the dial there appears to be different colored swatches. The top right is yellow, top left green, bottom right blue, and bottom left red. These are used to calibrate the Panorama Camera for any forthcoming Panorama images. Unfortunately, there had been no quality Pan images taken that day to show you.

As you can see, the martial soil is red, the basalt rocks give off a dark bluish tint, which in reality is simply a darker color. The martial soil seems to have blown up onto the rover as you can see the soil all over the sundial and surrounding hardware.
