BL504 is yet another colour hard to describe - is it blue? Indigo? Blurple? It doesn't look quite as saturated as this IRL, the creme base has a little bit of smokey hue in it. The glass flecks in this one are iridescent, changing from blue to very pinkish purple.
I love the scaly mermaid effect that Nfu-Ohs give but boy do they make my nails look chunky! ("Do my nails look fat to you?" *lol*)
