Maybe it is just my untrained eyes, but that ddoesn't look like it has a very high color count. I'm too lazy to run it through an image editing app, but I'd bet the pce could pull this off. Creative use of colors, not excessive use.
Yeah, you're right. Only 48 unique onscreen colors were needed to render that (
that is, according to PaintShopPro's "Count Colors Used" option). That's a helluva trick! I figured way more than that.
