NOTE: THIS IS NOT MY WORK!! I mirrored some code
available at http://www.conterra.com/drdata/bl/color3.html
and even there the code
was borrowed. I think that this setup is GREAT!!! Unfortunately, I cannot
seem to get to the site when I need to, it always seems to be down. So
really this is for my personal use, and I strongly recommend visiting the
original site mentioned above. Thanks! The Converter used with permission
