Deep purple. And always avoid yellow for two reasons 1. It wouldn't look right with tan skin. 2. As it fades it make your nails look like there rotten but a deep purple or or neon blue should look amazing
I love neon nail polishes!! Go to Dollar General in their makeup/beauty isle, and check out their nail polishes. They should all be LA Colors, and they're all only one dollar each!! I'm currently wearing a neon hot pink. It's called "Magnetic Force."
