I really wanted to like this gloss, especially because it has the words "full couleur" in the name. However, it's not pigmented enough to wear on their own to show up on my rosy lips.
I tested #4 at Sephora, which is a bright fun fuchsia color. On my bare lips it adds a slight pink tint to my natural lip color, but I think it would show up better after my natural lip color has been blocked out with concealer or a nude lip stick. Definitely not "full coleur" like I expected, although it is a really pretty color. I just wished it went on more as a liquid lipstick than a sheer gloss. I do like that it's mentholated, but it could get annoying after several reapplications.
