Rescue Beauty Lounge An Accidental Interloper is a moderately cool-toned, medium-dark gray with a metallic finish. It is a limited edition nail lacquer that retails for $20.00 and contains 0.5 oz.
Rescue Beauty Lounge An Accidental Interloper Nail Lacquer ($20.00 for 0.50 fl. oz.) is described as a "silver with an edge faceted by multi-shimmer hues." It's a darkened, charcoal gray shot through with silver shimmer and lots of it. It was opaque after two coats, and the consistency was not too thick or too thin (but thinner compared to the average polish by the brand). The formula applied fairly well and had minimal noticeable brush strokes as it self-leveled nicely. MAC Grey Friday is the only shade I have that is remotely similar, but it is more of a blackened gray with silver shimmer, but not metallic shimmer. See comparison swatches.
