Carolyn New York is a line of nail polishes inspired by the five boroughs of New York City, with colors including Spanish Harlem and Sunset on the Hudson. (No Williamsburg or Park Slope, though.) I haven't tried these, but since they're half-price, what have you got to lose? Through the end of the month, you can save 50% on nail polish (normally $6.99) when you shop online with the code CNYSUMMER. If you try them, let me know how they work!
