I chose the color Tropical Temptation by Revlon. I bought this about a year ago at Big Lots! I have actually bought quite a few Revlon nail polishes from Big Lots because mine sells them in a 2 pack for $2! So that makes them a dollar each! It is a good deal even if you only like one of the colors in the package. I would definitely recommend checking out your local Big Lots to see if it sells them too.
Let me know what your go-to nail polish color is for summer 2012 in the comments!
