Parade of Peacocks!

Index and Pinky: Spoiled - The Parking Meter Expired
Middle: Kleancolor - Retro Green
Ring: Essie - Dive Bar

 Kleancolor has the least shimmer. It's a really pretty blue-green that leans a lot green. No color shift or anything, but still a pretty sweet color. Consistency is just right.

 I love Dive Bar! This is the "walmart" version. It's a pretty blue-green shimmer with a very slight purple shift. It's a little thin which makes it a bit messy to apply.

I have to say the Spoiled is the real stunner here. It's a perfect peacock color. More pronounced purple shift to it. The consistency is a bit thick, but you could almost get away with using only one coat.

Verdict: None are dupes although the Essie and Spoiled are close.
If I had to get rid of one: This is a tough call. But, I'd have to say the Essie.
