Ahhh I've had this polish for a few weeks now and haven't gotten a chance to swatch it out because my crap long acrylics and my 30 day challenge. But here's the scoop: School of Hard Rocks from Essie's Winter 2011 Collection is a creamy, slate blue/green/grey polish that glides on smooth and opaque in just 2 coats. I was sorta worried as it's been sitting upright in its drawer for at least 3 weeks and it had already settled at the thin liquidy stuff rose to the top. I gave it an extra few shakes and it was good as new. The first coat was transparent and streaky, but it coulda just been me, as my hands are very badly sore from 3 straight days of crocheting Xmas presents. I love the color, it is such a new shade of blue/grey/green (lol) that I really haven't seen before. I instantly felt like it was winter and it made me feel very warm inside. The only problem I have with this polish: when I was applying top coat, the polish started to rub off onto the top coat brush!!! And I'd had my nails dried for nearly 45 minutes! Maybe it was just this top coat, I'll let you guys know next time when I use a different top coat. But my review stands: this is a great new color!! I love it, and can't wait to try the other Winter 2011's from Essie!
