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.

Plain files could just be left at the default face, no?  That would
leave us with directory, symlink, executable, and
backup/product/clutter, 4 colors.  Maybe also add archive, which
yields 5 colors.  Makes sense?
