Nighttrain is described as a "charcoal grey with crystalline frost [with a Lustre finish]." It's a blackened gray with silver shimmer and a frosted finish. It had fairly good color payoff, was just slightly dry, and blended out decently. It felt more like a frost than a Lustre finish. It is also a repromote. MAC Deep Cravings is less shimmery. LORAC Slate is bluer. Urban Decay Asphalt is similar. Urban Decay Ace is slightly cooler-toned. Urban Decay Gunmetal is grayer. See comparison swatches.
