Here is a small Gallery of colored MOC images as a tribute to the phantastic Voyage of the MGS spacecraft for bringing home such visions of an alien, frozen world made of red dust and black dunes

No idea how you DO that, just glad you do.

I'm curious to see how you do to process this pictures

Well actually there is no single recipe for how I do the processing of the images.
This is because the problem of coloring a single-channel b/w image is, unfortunately, an inherently "ill posed" task that does not have a unique solution (obviously because for each grey tone (luma component) there are many different possible color values (chroma component).
So, basically, what I'm trying to do is to work with many pre-chosen palettes of color hues collected
from "real" true color composite photographs of areas with similar surface composition etc.
and try to assign color hue ranges to grey-scale ranges.
However, this process involves a great part of guessing, tweaking, trial and error and last not least
the support of a collection of special software tools that I wrote (partly for fun when trying to
play with new image processing algorithms based on neural networks and various 3D color space transformations ) for example special adaptive brushes that help me with fine-selecting & masking parts of
the images by automatically following contoures/edges and so on.

All in all its tedious but geat fun and relxation to work with those colors & images: it always reminds me of the joy I had as a child when coloring pictures in the painting book
