Definitely black
Admittedly it's been a while since I've used lipstick, and when I've used it in the past it's been regular stick lipstick rather than the liquid kind, but I had to go over my lips several times to get opaque coverage with this stuff. It's quite black, no problem there, so if that's your primary concern you don't have much to worry about. But you do have to use a lot to get there, and it wipes off pretty easily (again, I'm comparing this to solid lipstick, which is harder to remove). So all in all I think I'll stick with solid lipsticks in the future and leave the liquid kind alone, but your mileage may vary. Oh, and it does taste a little like chocolate, which I found unnecessary and kind of weird.
