Essie's School of the Hard Rocks. This is a dusty gray/teal/evergreen. Really, the product in the bottle doesn't do it justice. Applied, this is a very unique and beautiful shade. This falls into the "greige" category, only on the green side - maybe a "greenge"? I will say, this was a bit of a difficult color to capture in pictures - it looks more blue in the pictures, and is a bit more green in real life - but you get the idea.
I wanted to add a little bit of a festive look to this color, so I used one of my CinaPro Nail Decals in Peppermint Twist, which I found at Sally Beauty. They are adorable, and this set has candy canes, snowmen, wreaths and gingerbread men. There is another one exclusive to Sally that has Santa, Rudolph, and other festive decals. I believe they retailed for $3.99.
Back to the Essie - the formula is one of the nicer formulas for Essie. This is smooth and shiny and coverage is very nice. Above is two coats of polish with one coat of top coat. I would put this polish as one of the "must have's" for you - it's different enough, but also very wearable.
Have you tried this color? What other color from the collection have you picked up?
