Neither graphic art, nor the human eye, is as linear as you think.
And this IS ntsc we're talking about.  DCTV isn't 24bit, it's only got
about 4 mil onscreen, and then the luminance transitions are faster
than the actual color transitions.  And it would probably look better
than a 24bit RGB, simply because it's pure NTSC.  The bits aren't
there, but you see my point.  It's not linear.

Not on your average TV...  And CDTV looks better than I thought it
would.  Far better.  I had expected Amiga graphics, and they didn't
look like Amiga graphics.  I can't explain it, but they didn't seem
the same.  It was on a TV I was viewing it on, and it did look good.
Have you ever seen CDTV?  No.  :-)

Okay.  Now you can hold on.  Who the hell ever said they were
COMFORTABLE????  I'd love 8bit graphics.  I don't want a 24bit graphic
chipset.  It's a bad idea.  That's for graphic boards to handle, and
for DIG to deal with, IMHO.  What is needed now is an 8bit graphic
chipset to compare directly with VGA.  Argh.

And what the hell do you want me to do?  Design my own chipset?  Pay
me, and I will.  :)  I can see using a nice 4x4x4 tower as my new
Denise.  :D
