A Sprinkle of Blues #1 is a pale, cool-toned white that flashes blue. It’s very, very sheer and powdery–it was almost chalky–and difficult to swatch, let alone apply. It clumps if you use it wet, so I wouldn’t recommend applying it with a damp brush. Disney by Sephora Sick of Swimmin’ (LE) is very similar. Maybelline Waves of White (LE, $6.99) is greener. MAC Vellum is whiter with a less pronounced iridescence. See comparison swatches.
