Counting Unique Colours

I need to work out the total number of unique colours in some TIFF images. Does anybody have any links to command line utils that can do this? Or, better still, some code that can do achieve this using Core Image or Quartz Composer?

I've tried using the pixmap info in GraphicConverter but don't trust the results.

Oh, and while I'm on this subject, has anybody got any apps or code that will parse CMYK images for total ink limit? I used to like the way that MarkzScout could do this in automated workflows - but haven't used that for many years.

Regards
