Between 13:29:39 UTC and 13:30:54 UTC Opportunity’s Pancam takes three images with narrow band filters in the three basic colors, from which it was possible to derive this beautiful true color image of the Martian soil and rocks.
In this case, the original images (especially in the green and blue) have a high level of “noise” and so I applied a median filter to all three colors to eliminate spurious dots.
Still very interesting color variations, not only on the rocks but also on the ground!
