I have this in Sheer Streak. It's a pretty light-to-mid tone pinkish coral on me (but since they're sheer, your own lip color will peek through, possibly altering the shade). It's balmy, comfortable to wear, and looks lovely on -- just a nice, glowy, juicy lip. Sheer Streak does have a tendency to cling to flakes and lines but it's not too bad (judging from the below reviews, there seems to be some variation on this depending on which color you get). It does fade quickly and needs frequent reapplying. I think I'm just spoiled by all the longwearing mattes I've been wearing lately, etc, since I do find this annoying but it's to be expected from this kind of formula. Very moisturizing though.
UPDATE: I've been playing around with this, and it looks really good over a stain. I use it over BeneFit's Cha Cha Tint, which barely shows up on my lips, and it's great. It adds more color and something for the lipstick to hold on to.
