Ultra Violet by Bear Pawlish is an insanely holographic, super bright blue-toned purple. Probably one of my favourite polishes at the moment. I can't quite get enough.
The holo is still strong even when you aren't in direct sunlight. Nothing worse than a holographic polish that looks grey when not in the light. I'll definitely be pulling this one out in the summer, though. How can I resist?
I have applied two coats plus top coat. Beautiful formula and finish. Easy to apply and no problems with staining (I do have a layer of Essie's base coat on), even with this rich colour.
You can buy Bear Pawlish here (but right now it looks like the site is down).
