The Lights of Emerald City has a clear base filled with matte white and iridescent squares. This is two coats over Essie Ballet Slippers.
The formula is great--no fishing or placing required, which are always my two biggest concerns with glitters like this one. There seems to be a good ratio of matte to iridescent squares. One element never overpowers the other and the two finishes create a fun contrast. I love the soft, delicate look Lights of Emerald City gives off over a pale base like Ballet Slippers but really, I think it'd look good over just about anything! The iridescent pieces would work beautifully over a darker base, while the white squares would really pop over a fun summer neon.
I'm thrilled OPI put out a polish like this! Matte and square glitter in a mainstream polish? Yes please! There's nothing else in OPI's catalog even remotely like Lights of Emerald City, but I hope it's a sign of lots of fun, unconventional sparklies to come!
