Cult Nails Intriguing Nail Lacquer ($15.00 for 0.30 fl. oz.) is described as a “periwinkle with gray tones and some holographic shimmer.” It’s a faded, medium, gray-tinged blue with very fine white shimmer. The shimmer appeared holographic in the bottle, but I couldn’t see it on the nail at all, no matter whether I was outdoors or indoors. The consistency wasn’t too thick or too thin, and it was opaque after two coats. Chanel Sky Line (LE, $27.00) is metallic, lighter. Zoya Skylar (P, $9.00) is darker, more shimmery.
