I hadn't ever thought of painting another color over black before. Then I saw someone else with these colors on, but they were much more vibrant. When I asked her why, she said that they all looked better over black. So here's what I came up with.
Sally Hansen's Cyber is the purple, and Sally Hansen Resolution is the green.
They Are both over top of Orly Liquid Vinyl.
I added some China Glaze Black Crackle overtop with some Seche Vite topcoat.
Resolution definitively is the better color with the crackle, but they are both amazing over black.
