This is Yves Rocher's nail polish in 21 Mauve. It's a light lilac color with a fuchsia sheen.
In brighter lighting I get a lilac/fuchsia, and in dimmer lighting I get this super flattering nude color.
My issue with this polish is that it's quite sheer and I need at least 3 coats.
Overall I'm very happy and I'm glad I've found a lilac that works with my skin tone.
