Tony,
Ah, I get you now. The font dialog is actually the shared Windows font dialog just with some Global Mapper-specific controls added at the bottom. The color selection is part of the common Windows implementation and not something added by me. It is kind of curious that they only have a limited selection of colors there, but I've looked through the flags for creating the common portion of the font dialog and can't find anything to allow selection of any 24-bit color.
Thanks,
Mike
