​ow can this work?​ The author in this text has to support every changeable
property for every possible combination and ensure everything works fine.
what if the user picks black on black... there will be a loss of
functionality... but even if we plug that hole... its way too much to
support 256,000,000 colors for both foreground/background, and hundreds of
fonts.

I think we have to go with some sort of "C" or "G".
