A NOTD from a few weeks back, Essie "For the Twill of It", from their Fall 2013 collection.  This is a dark metallic with magenta, teal and green flashes.  A bit thin, but after two coats it seemed to cover nicely.  

I will say, I want to wear this one again now that my nails have grown out.  I don't care for this on my short nails, but I think on my longer nails I would like it better.
