The messed-up color calibration? The German fellow appears to be correct WRT those images. I don't know if this is just sloppiness while getting public images released, or if some PR person advised them to skew the calibration to the red for publicly-released photos, probably figuring that some sector of the mainstream public audience wouldn't believe that it came from Mars otherwise.

Anyone using those images for research is going to take the targets and do their own calibrations, anyway.
