Butter London Branwen's Feather is a slightly cool-toned, very dark purple with a pearl finish. It is a permanent nail lacquer that retails for $15.00 and contains 0.4 oz.
Butter London Branwen's Feather Nail Lacquer ($14.00 for 0.4 fl. oz.) is described as a "purple-ish black with loads of depth and shine ... like a silky raven's feather at midnight by the Tower." After reading the official description, I can see what they mean. It is a very blackened eggplant-y purple with flecks of plum and silver shimmer shot through. It dries slightly shiny, but I would still say you need a top coat to really make it gleam.
