The original Birefringence is one of my favorite nail polishes. And Birefringence with Holo is just as awesome. It almost glows with the addition of the holographic sparkles. There are so many colors in this polish depending on the angle of your hands. (2 coats, plus 1 coat Seche Vite topcoat).
For comparison here's the original Birefringence and it's Holo version:
Washing Ashore is a gorgeous blue green duo chrome. It's pretty much everything I wished 'My Little Glacier' would have been. (I ended up selling that color on eBay). Washing Ashore reminds me of peacock feathers or the ocean. I love it! (2 coats, plus 1 coat Seche Vite topcoat).
Sweet Serenade was a little darker than I thought it would be. It reminds me a bit of an oil slick. You see dark blue, almost black, green and purple. It's more subtle than the others but still gorgeous. (3 coats, plus 1 coat Seche Vite topcoat).
And last but not least Absolute Zero. A deep navy blue with silver shimmer in it. (3 coats, plus 1 coat Seche Vite topcoat). This was a limited edition color, only available to customers who pre-ordered 3 or more of the new polishes.
