After having discovered the proper calibration process for the black&white CTX images (thanks again
to slinted, cartrite and others for the valuable contributions !) I found that many of the cleaned up CTX images with the increased dynmiac range are
very well suited candidates for artificial colorization. Here are the first results:

A martian polar dust storm over ice dunes


and a crater landscape with central mountains:



Please keep in mind that, as always with artificial colorization, the colors, although I usually do base the palettes on "real" color images of similar areas with similar surface composition, are, of course not intended to reflect the "true colors" but rather be understood as a kind of "artitst impression"

I'm enjoying these too, but I expected the dust clouds to look yellower, relative to the surface. Have I been looking at too many Chesley Bonestell paintings?

Here are another two of my favourite CTX images found at the great Mars Global Data Image Archive, calibrated and colorized:

That second one in particular is just insane... should really be in a gallery.

Dokka crater from CTX camera (NASA/JPL-Caltech/MSSS). Color is from MEX' HRSC images (ESA/DLR/FU Berlin).

Second image is again from CTX and colorised from HRSC images.
This crater is lowest place on Mars (if it is referenced to the areoid).

Color is more or less artistic impression, partly because of completely different light condition in first image (low sun (CTX) vs. high sun (HRSC)) and massive haze in second case (after all it is place with highest atmospheric pressure). Resolution is reduced to ~13 m/pix (resulting images had higher dynamic range and after adjustments much higher contrast).
Both images are part of my blog entry about lowest and highest places on Mars.
