Strictly for Cover 4 - yes and no. If memory serves, Quarters, Show 2, and Palms all do have pink Quarter Flat zones where Drop does not. But, as far as which zones technically match, looking for pink isn't going to help much with understanding the playcall. In Quarters (so also Show 2) specifically, those pink Quarter Flats are actually the least likely to match up into man coverage instead of playing their zone as indicated in the play art. Other match coverages like Cover 3 match I guess do have pinkish-purple zones, but to the best of my knowledge every 3-deep match play at least has "Match" in the title. So I suppose moot point there.
