Hopefully Hatari uses standardized colors that can be corrected by
the display that they are used on.
It may be possible for Hatari to have a customizable palette too.
I believe someone should measure the color DAC voltages
(with monitor connected) so that Hatari can output video voltages
for historical purposes.
