Take a look at the beauty that is ILNP's Birefringence! This is the scattered holo version (there is a non-holo version as well but why bother with that?). This polish applies like a dream, and check out that color shift! It's mainly blue to purple, but you can see some gold in the bottle and it peeked out occasionally on the nail. I just couldn't capture it in the photos. This is three thin coats, plus Essie First Base base coat and Seche Vite on top.

Birefringence is available at ILNP's website for $12.50 plus shipping.
