Same, with Chanel Peridot on thumb.
So, there's some obvious differences...Peace is lighter and more yellow/gold, whereas Agro is more of a dark, forest-y color. I'd say they're in the same family, but definitely not close to dupes. They are both really shiny though, and have the same type of shimmer in them. I also felt the need to throw Peridot in there just to see how it compared...not really close at all, besides the fact that it's also a green/gold type shade.
So, it's definitely not a bad thing to have both Agro and Peace...they're both absolutely gorgeous, unique colors! But if you have one of them, I'd say it's ok to skip the other. I love both, but I do have to say I think I like Agro a little better...only because it's a little darker and more green instead of gold. I just can't pull off gold, unfortunately!
