Birefringence

Blue to Purple Ultra Chrome Nail Polish

I do not possess the linguistic capacity to express the “awesomeness” of this nail polish. But for you, I’ll try.

Birefringence is a jaw droppingly beautiful polish that effortlessly stops people in their tracks. Planning on having a meaningful face-to-face conversation with a friend? Plan on an abrupt derailment as soon as he/she notices what your nails are up to. Remember though, it’s not their fault; you were warned!

Birefringence shifts through an array of incredible blues, purples, reds, oranges, yellows, and even subtle greens!

Birefringence is part of ILNP’s Ultra Chrome™ class of chromatic nail polishes; formulated to apply directly to the nail without the need for a base color.

Fully opaque after 2 coats!

Fun shift

I really like the lighter blue, shifts to gold and red (similar to Cygnus Loop, but less noticeable). Cygnus Loop has the stronger shift and the darker royal blue, almost purple in some lights. Personally I prefer the blue in Birefringence but I like the stronger shift in Cygnus Loop. I had a few bubbles applying this one, didn't have that problem in any other ILNP except for Cygnus Loop (and that may have been a problem with the base coat). I like putting this on some nails and Sirene on some others--they have the purple shift but then go to either green or blue, it's a fun unexpected flash of color depending on the light. 2 coats for opacity, lasts a long time for me (about 5 days, and I'm rough on my nails so this is good).

This is my first chrome polish and I adore it. The color shift from blue to purple is very fun but even when the light it more subtle, the color is always beautiful. Lower light - blue leaning purple. Sunlight - more true purple.
Wow!

This is THE polish I would take with me to a dessert island. I wear it over black or navy blue so one coat is all that needs. I am Into my fourth bottle now and Will buy à new one next month. I cant menage without it
