YSL Gris Underground (38) La Laque Couture ($25.00 for 0.34 fl. oz.) is described as a “cloud of grey.” It’s gray, blue, lavender; a muted, grayed cornflower blue to me. Very cloudy, very fall. It was opaque in two coats, and the consistency was just slightly on the thicker side, so the drying time seemed longer than average. It applied fairly easily, particularly because it has a wider brush that enables better coverage in a single stroke so it minimizes unevenness. The formula isn’t forgiving if the prior coat is only partially dry, so make sure to allow enough time between coats for drying. Essie Rock the Boat is lighter, slightly less gray. NARS Galathee is much grayer. See comparison swatches.
