   Color assignments (foreground,  then background,  in hex form)
   These apply to Windows Find_Orb and most modern Linux/*BSD/OS/X systems.
   Look below for colors to be used on 8-color terminals.

   Color assignments for 8-color terminals.  Here,  we just have the
   eight primary colors available.  Note that under most modern systems,
   it's possible to tell the terminal that you really do have full colors.
   'export TERM=xterm-256color' usually will do the trick.
