Thnx,
It was the damndest thing. My comp was on the fritz. For some =
reason, the prog worked just fine with the hex values, but if I used a =
numerical value instead it would just be black. I had other strange =
problems too. But I solved it all with a reboot.

This is a common misconception. Hex, binary, decimal, octal, and even =
ASCII characters are all different *representations* of the same number. =
When passing colors as atoms, it doesn't matter whether you use hex or =
decimal. If I say 255 or #FF, it's the same. Many people are just more =
comfortable with hex representation from programming HTML. On the other =
hand, when passing as strings, it may be quite important which format =
you use depending on how the routine parses the string. But as you =
already mentioned, sprintf handles that situation quite nicely.
HTH,
