## Prep a temporary filename, to hold the list of color names.
##
##      We put the outlist file in /tmp, in case the user
##      does not have write-permission in the current directory,
##      and because the output does not, usually, have anything
##      to do with the current directory.

  The list above was generated by the script

  in directory

$SCRIPT_DIRNAME

  using 'showrgb', 'grep', 'sort', and 'uniq'.

  If you want to change the presentation format or the sort,
  you can simply edit the script.
