README.MAPS:

  TRANSPARENT:  Color to remove from the background (make it transparent).
     Use a number, 0=black.  Color-mapped images use the map value, so
     white is usually 0xffff.  Value can be decimal or hex if preceeded
     by "0x".  Multiple TRANSPARENT lines can be used in a file to make
     multiple colors transparent.

I used to use "xv" to do it.  There's a way to have it tell you the
color value when you click on a pixel with the mouse.  You can also
really enlarge the picture so that you can click on just the right
pixel.
