Hey! I just went to a beauty store yesterday called Ulta, and by the way, everything there is too Expensive! Anyway, I got Two polishes. One is a cool lime green sort of color by China Glaze. It's called Entourage.
The second polish was a black crackle top coat by Sally Hansen. That would look really cool with a neon, or neon gradient background! I'll get back to you on how well it works
