Essie's Passport to Happiness
This is a unique color in that fact that it's not quite blue, it's not quite green, but it's not exactly a blue-green shade. It's similar to their Mint Candy Apple shade, except this one has a blue iridescent.
If you really wanted to, I think you could get away with this shade being your "something blue" if it's your big day. Essie describes this shade as a "whispering spring green," but like I said, it's a unique color. I can't quite describe it. It looks blue in some light and green in the others.
This shade will look beautiful on all skin tones! Personally, I'm really digging the way it looks with my tan.
You can get this shade for $8.50.
