My recall of the color pallete in CGA mode was that
the "dark" versions of
the main colors were a bit flip from the main colors and that "brown"
Correct in general, that bit corresponds to the I line to the monitor.
really was "dark yellow." You could call it
dark yellow all you wanted
(and some docs did) but once painted on the screen, it was brown. I think
white with the corresponding bit set (cleared?) was gray. Or was dark gray
equivalent to black...? I forget. I recall that something about it was
logically wierd and didn't make sense.
Well, colour 0 is black (all bits off). Colour 15 is light white (all
bits on). Colour 7 is either normal white or light grey (depending on
what you want to call it!). Colour 8 is grey in the IBM manuals, you
might think of it as light black. It actually does make sense if you look
at the hardware.
