I actually put a "more than 6 colors" demo and hi-res screen shot onto the
CiderPress tutorial disk.  IIRC the IIgs RGB display does show the "extra"
colors, so it's possible to get consistent results across different monitors.

The key to all of these is probably to transform from pixels to some
representation of a signal, and then pretend to be an NTSC display device
to convert back to pixels.  Might be too slow for an emulator, but it could
certainly work for static screen shots.
