Exotic Purple is described as a "dark navy [with a Satin finish]." It's a blackened navy blue that leans a little purple with a satin sheen. It was semi-sheer with a drier, thinner consistency that made it hard to work with. It was a shade that tended to look uneven when applied to the lid. It lasted for seven and a half hours on me. See comparison swatches / view dupes.
