  I don't agree with this. Most Amiga graphic programs store images
internally as 24bits and most load/save IFF24 bit images, however
the standard Amiga can only quantize these images to 4096 colors.
The NeXT hardware palette is 12(16?)bits, period. It doesn't matter if the
OS stores pictures internally as 100 bits, the hardware is only
capable of 4096 different colors.

  You can't simply average the software and hardware together and
say 'it's somewhere inbetween.' The hardware determines what
kind of palette the machine has.
