Re: [ferret_users] Fancy line/label colors

[mick spillane <mick.spillane@xxxxxxxx>]

Hi Jaison,

   What a great utility -- especially to someone like me who has a bit 
of trouble with colors and
palettes.  It may be that I don't understand it completely yet, but I 
had to set an alias

      alias showrgb '/usr/X11R6/bin/showrgb /usr/X11R6/lib/X11/rgb'

on one machine and on my Mac

      alias showrgb '/usr/X11R6/bin/showrgb /usr/X11R6/lib/X11/rgb.txt'

to get rgb_colors to  brighten my day.

Congratulations and thanks,
Mick
