If you have 256 colors available, then the possible color
indices are 0 - 255; you are requesting a color that is
"out of range". It looks like your system is changing the
visual class for you when you request a color that it
cannot provide.

This seems too easy. Please excuse me if I'm having a
"technically challenged" day.
