Even when you limit the depth to 3 then you can still get a high or true colour
screen.
I did a DisplayBeepPatch for P96 where I needed to flash the screen and used:
SetDrMd(rp, COMPLEMENT);
RectFill(rp, 0, 0, width-1, height-1);
This EOR every pixel. which I assume is what you want.

uhh... as I've vaguely stated before - I just love these programs which make
assumptions about how I want to use them ;-) If you screen is a public screen
then I'd definetely open other programs on it, like MUI programs which with my
setup require more than 8 colours. If it's private then I love the program
even more... 8-)

And that'd give you a 16 bit screen, but with a pseudo palette with 8 entries.
