Beacon Nail Lacquer ($12.50 for 0.40 fl. oz.) is described as a “royhal blue micro-glitter in sheer blue.” It’s a deepened–but still bright–medium-dark blue with lighter blue and purplish shimmer and sparkle. The texture is smooth to the touch, and the finish is shiny–foil-like. It was fully opaque after two coats. I also tried one coat over black, and it can work, but you can see how one coat is quite dense. Zoya Dream (P, $9.00) has larger shimmer, more muted. Marc Jacobs Beauty Blue Velvet (132) (P, $18.00) is more muted. China Glaze Blue Year’s Eve (LE, $7.50) is lighter. Zoya Song (P, $9.00) is bluer, brighter. See comparison swatches.
