it's not about how much colors on screen, it's about how the colors are used.
and NARC uses 'em in a real horrible way. if that is one of the most colorful games the US can bring on the table, then good night dear sir.
for me also the outrun coloring is looking so much more delightful as those from road blaster, still road blaster is not the worst example for sure. it was just a racer, as well from about the same time.
You gotta compare apples to apples nuts. Even though road blasters came out about a year after outrun, it's running on far inferior hardware, at least colorwise. We are talking a palette of 12288 (outrun) vs a measly 1024 (roadblasters). Less colors available means more clever usage of available colors is needed, the fact that side by side the two games look like they are from the same era when outrun has 12 times the number of color choices says a lot for roadblasters. In fact outrun should be ashamed it only looks about 2-3 times as good instead of 12 times. That being said, you can hardly blame it on poor programming skills or talent. Like chop said, we are cheapskates, we cut corners whenever we can to maximize profit.
In fact I think Narc uses it's colors far better than final fight. Yeah final fight used some brighter colors and it seems to "pop" out at you more, Narc makes good use of it's palette of 8192 (which in this case is more than final fight's 3072) with smooth gradients and blending. Imo the extra colors available shows. It looks a lot more natural than the blending of colors on final fight; just look at that thugs green and black pants, ick. Final fight is more a different style than anything (bright and cartoony) whereas Narc is more about subtle details, smooth blending, and more natural looking graphics. The detail in Narc's graphics is amazing, while it might not be the super colorful bright in your face type, I actually prefer it in this case.
If I had to say what took more work and talent to draw out, I'd say Narc hands down, just take a look at this screen:
Look at the fine pixel details on the trains texture, the reflective look on that pillar and ground, and all the different shades on the bad guys coats. I mean just look at that ceiling. It almost looks like real life objects that were down sampled to fit the games limited palette, but still doing a great job. The only real complaint I can see about Narc is those big expanses of solid color in the background, and honestly with the level of detail on everything else, I hardly notice. It's really a matter of preference.
