Monday and I'm able to come up with something at least some what blue. I bought this polish from Pretty & Polished for awhile ago and it's called Boy Bleu. It's blue opaque glitter and black opaque glitter in different sizes. There's also some occasional very large silver hexagons in it and all the glitter is in a clear base.
I don't know if this counts in Lindas Nailorama's Blue Monday theme, we'll see ;) Anyhow, more blue polishes can be found at her blog in a link list later to night.
Ninja Polish - Humble Bee which is yellow and black glitter in a clear base. I've also seen Boy Bleu in a manicure where it was on it's own and covered, so either that was 10 coats or the polish has been reformulated with less glitter. And while I'm at it, I don't like the large silver hex glitter, there's too few to make any difference, they're just in the way.

Do you got this polish or the pink variant of it and has is covered on it's own for you?
