Rastan screens are better than the final fight ones you posted before, still too saturated and eye-popping. Your eyes will bleed if you play with these reds for an hour or so. Cannot really tell the difference between foreground/background.
You have to drop parallax scrolling I suppose to make them work though except if you use some tricky copper effects like the ones in Lionheart or some tricks used in Risky woods. You really need a top coder to have this results on Amiga 500.
