I received this Essie nail polish in Stylenomics from a Klout Perk a few weeks back. I admit this is a very overdue post, but a late post is better than no post! I opted into the perk and received it 3-6 weeks after the perk was closed. I wasn't sure what shade I would be awarded as colors are just randomly chosen and sent off to those selected.
Stylenomics is from the Fall 2012 collection. According to Essie, Stylenomics is a very dark green creme polish. The polish appears slightly green, but it really looks more grey/brown-black than anything else. I admit I have not worn this on my nails as of yet.
