Hola :-) The other day, I received Revvolution by Color Club as well as Wild At Heart which I still need to try. When I first recieved the bottle, it didn't seem to have much of a holo effect but the application is sooo much more interesting. It's a blackish dark grey with a nice holo shimmer. I've seen people compare it to My Private Jet by O.P.I but say it looks even better.
I also really liked the formula. It wasn't streaky at all and I didn't end up with any bubbles. It also dried really quickly. These photos have 3 coats of Revvvolution and 1 coat of Seche Vite.
The photos below are taken in direct sunlight. It is such an interesting color up close and I've never owned anything like it.
