   If the terminal supports 16 colors, it means Emacs is not being told
   about that.  Are you sure your TERM variable points to the correct
   terminfo entry?

   Anyway, this is a separate problem.

It is set to wsvt25 -- which is the default.

   Plain files could just be left at the default face, no?  

Yes.

   That would leave us with directory, symlink, executable, and
   backup/product/clutter, 4 colors.  Maybe also add archive, which
   yields 5 colors.  Makes sense?

Yes (though I don't understand why archive needs to be a different
face -- but that is a different problem too).  I think it would be
useful to differentate at least "special"?
