I've showed this polish on the blog before so you probably know it by now. It's KBShimmer Myth You Lots, a beautiful blue/purple holo with an amazing duochrome effect. If you wanna see more pictures of the color shift you can check out the original post. There's also some of it in the following light box picture.
I can't get enough of this holo! I really hope there is a lot of sunshine in your spring so you can enjoy life and nails. Have a great weekend!
