Firm Form is a blackish-brown with a dusting of gold micro-shimmer. It looks a little purple-ish applied, as the lipstick mixes over my natural lip color. It is pretty opaque, and though it does not apply perfectly evenly, it does apply considerably better than a lot of other lipsticks in this shade family. MAC Grey Friday is grayer, lighter. Chanel Hysteria is cooler-toned, blacker. MAC Smoked Purple is much purpler and lighter.
