Between 20:22:53 UTC and 20:23:54 UTC Opportunity’s Pancam takes three images with narrow band filters in the three basic colors, from which it was possible to derive this extraordinary true color image of the Martian soil furrowed by a tangle of tracks left by the rover itself.
In this case, the original images (especially in green and blue) have a high level of “noise” and so I applied a noise filter to all three colors to eliminate the spurious dots.
Another example of reddish soil covered by a greenish-blue layer, but this time also with some white material mixed in with the soil.
