I had been incredibly underwhelmed at China Glaze's Hologlam collection. (I'm thinking Color Club's Halo Hues have ruined me for any other linear holos) But as swatch photos started popping up, A couple of them caught my eye.
The holo particles in this collection are much finer than some of the in-your-face holos we've seen lately, lending to their more subtle appearance. When Starts Collide is a plum purple base packed with holo.
Application is tricky. Thin coats are key, as is waiting a couple of minutes between. I used a quick dry top coat and found that the effect diminished slightly at first, but came back strong when completely dry.
