Silver Gull is a pale, neutral-toned gray with silver sparkle. This has a velvet finish. The base color has more of a matte finish, while the sparkle lies on top of the product, which does cause significant fall out (even just swatching, the sparkle doesn’t bind with the actual color). It’s also on the sheerer side and a bit powdery. Guerlain Les Ombres de Nuit has a slightly similar gray. Unfortunately, I couldn’t think of any other dupes.
