This is my fave red lip color!
I believe it works for any skintone from light to very deep. The forumula is excellent as well. It doesn't smear all over the place either...you can have a bite to eat and still get good wear. It can work with or without a lip liner. I prefer to use a lip liner with it.
I am NARS Macao and NARS Tahoe for reference.
The 2nd best I've tried is Dior Favori Red, but I have some sort of sensistivity to the lipstick...not sure what's in the ingredients...anyway, it's a killer red, too...but Chanel Roughe Allure Laque in Dragon is the best of the two.
