On my nails at the moment: OPI - Glacier Bay Blues (don't you love that name? I do! :L). This is a black label OPI, meaning one of their older polishes with the non-big three free formulation. GBB is a duochrome or actually a multichrome with a teal coloured base. Depending on the angle of your nails and the lighting you will see teal, a beautiful dark blue and purple. Those three colours are clearly visible in the bottle as you can see. The purple on my nails was hard to catch on camera, but it's definitely there! I like it very much. It reminds me strongly of Nubar Peacock Feathers, but that one is a bit darker, with a more mossy green flash instead of the teal flash GBB has.
The application was ok. You just have to keep in mind that it is a black label OPI (often thin and less pigmented). This is three coats with topcoat.
Thanks for watching! :h
