Art of Noise is part of Rimmel's new Underground line. The Underground line is similar to Revlon's Street Wear collection from years ago in that the m/u and nail polish is really unique and off-center to mainstream. These aren't everyday shades. This particular shade is the only one that bears a resemblance to any other shades to me. It's a deep purple base with orange fine shimmer. (if you want an indigo base try out Night Before). This shade resembles Zoya Yasmeen to me, swatched next to each other, Yasmeen's shimmer is more of a red-orange to AofN's orange, but are otherwise probably indistinguishable. Love the application and wear of these polishes, they're very pigmented and the brush is a wide, flat brush which helps with application. Non-streaking, unique, long-wearing shades, and I love every one I've tried so far.
