Um... no, they can't.
- The HiRISE images are just that: Images. The spacecraft /per se/ does
not make measurements of topography.
- The HiRISE camera takes images in the ~500 nm, ~700 nm and ~900 nm
bands; that's blue-green, red, and infrared. That's /not/ RGB and
therefore /cannot/ capture the true surface colour.
I guess what you mean are HiRISE DTM (Digital Terrain Models)
/generated/ from the HiRISE data proper. From what I could find, the DTM
format is a "32-bit [...] PDS standard raster file format."
If you really want this to be implemented, you can help a lot by digging
on the internet for a detailed description of the file format;
unfortunately I don't have the time for that.
