I had this problem a long time ago.

My solution was a shell script that looks up the colors, and replaces
the hex stringa with X window color names.

The scripts for this is part on my old "Anthony's Icon Library"
   http://www.cit.griffith.edu.au/~anthony/icons/

Specifically the script directory in
   http://www.cit.griffith.edu.au/~anthony/icons/support/scripts/Icons.html

And the scripts
    xpm-fix        Fix the X pixmap output from pbmplus (restore color names)
    color_db_mk    Create a reverse color name database (for xpm-fix)

These are also related.
    colorname      find the rgb.txt colorname of a pixel #rrggbb value
    color_lookup   Print the #rrggbb pixel value for a named X window color

The "color_db_mk" creates a small table of hex to color names dealing
with the fact that some hex values has multiple color names in the X11
RGB color table.

The "xpm-fix" uses the table to substitute the hex values with color names.

NOTE this is OLD stuff.  I make no guarantees.
