To start this month the right way, here's a nice dark colour, OPI I Brake for Manicures from the Touring America collection. It's the only shade in the whole collection that attracted me, a strange mix of purple and brown with some smokey edgy effect. It's perfectly opaque in two coats with a beautiful glossy finish that doesn't need a top-coat.
In the shade, it looks dark but not as stark as a black cream would.
In normal light, it looks purple.
But in bright light, you can see the brown showing up.
