(I put 'Raw' in the subject line for a good reason)
To answer your question, Mike, it depends on the filters and it
depends on the processing

This explains about the filters

This is an example of a (probably quickly) processed image combining filters

Those old colored Voyager rings images that NASA released took months
to process from the raw data (they had a special laboratory at JPL
devoted to processing images). Other colored photos that my old
photopolarimeter (PPS) group released were one-d stellar occultation
data, mapped onto the geometry of the rings to create a two-d image,
with a somewhat random color added. The PPS 'images' were more for
press purposes than anything else, since what the scientists were most
interested in was the spatial details of the rings.
