This is Royal Purple Color Flip.
This is three coats, with topcoat. The polish is quite sheer, but has a lovely jelly-like quality to it.
The polish is a bright pinky purple jelly with lots of shimmery blue-purple particles that give a blueish duochrome effect in the right light. The polish is much more purple in the bottle than it is on the nail, looking much pinker when it's applied.
This is really sheer - three coats still gave plenty of visible nail line, so next time I might try it over a creme base. I do think it's a really pretty colour though - it's bright and zingy and does have a lovely shimmer. I find it quite pricey for what it is though.
What I do really like about these polishes is the lid - it's a nice rubbery texture with a lined pattern which makes it really comfortable to hold easily.
