You are correct in that many software houses will put out all of the color
procedures that they define for their software.  But, the actual output may
never call them.  So, searching for the color keyword will result in hits,
but are the redefined procedures, that contain the keywors, really being
used.

I suspose the best way to see if it is in color is to run it through a
PostScript interpreter like pageview (for OpenWindows).  I don't remember if
GhostScript will display color PostScript, or B&W the output.

Warning: pageview has to be used at the low dpi settings, otherwise it will
display the output in B&W :-(
