Butter London describes this as a sheer, royal blue and indigo duochrome nail lacquer with pink, purple, and blue microglitter. I'd say they got this one pretty spot-on. It's a purple/blue duochrome that is, unfortunately, incredibly difficult to capture in photos. The shift is much more prevalent in person. Since Scouse is so sheer, you will have to use an extra coat or two for opacity. It doesn't go on quite as evenly as some of my other BLs, but it is insanely gorgeous once it's built up. These swatches show three coats of Scouse with Sally Hansen 30 Second top coat (and Essie Matte About You top coat on the ring finger).
