Arctic Grey is a frosted, beige-gray with more beige than gray. It is a more golden and shimmery version of Rainy Season really. It had decent pigmentation, but it has a Lustre finish, so it also has larger sparkles that were prone to becoming fall out during application as well as during wear. Giorgio Armani #1 Spring 2012 #4 is more metallic. Giorgio Armani #19 is lighter, more metallic. MAC Vex is grayer. See comparison swatches.
