Riot is described as “smoky gray matte with violet and fuchsia micro-sparkle.” It’s a dark purple with subtle warm undertones and flecks of violet, purple, silver shimmer. It had sheerer color payoff when I applied a single layer, but it was buildable to mostly opaque color coverage. It lasted eight hours well on my lash line, but it was noticeably thinner after nine hours of wear. This shade is new and exclusive. Urban Decay Empire is similar–slightly brighter. Urban Decay Delinquent is warmer, darker. MAC Permaplum is less shimmery. See comparison swatches.
