One of my favorite combinations is using different colors in that "holo"- like finish. Naturally, when I got Color Club Wild At Heart, one of those "holos", I had to do another one of those manicures. I was originally going to do this as a tape manicure, but I thought that would be way to time consuming. Plus my tape work is usually pretty sloppy, the opposite effect of what it's supposed to be. So I just settled for my usual brush detailing.
I used China Glaze Techno Teal, Color Club Worth The Risque, and Wild At Heart.
