Cirque’s Sin City is a neon red-coral. It’s super bright in person, and unfortunately it mostly just reads as “orange”.
This was almost totally opaque in three coats. The visible nail line in the photos isn’t nearly as evident in real life. I found the formula to be a tiny bit thick and difficult to work with, but it was so minor I’m chalking it up to the three fans I had going in the room I was in (hey, it’s Texas in August, yo).
