Because I've been asked to do so, today I have a comparison of Essence's nail polish 01 I'm The Moss from their current Guerilla Gardening LE to show you.
The closest color I could come up with is China Glaze - Starboard. It came out in Spring 2010 as a part of the Anchors Away Collection, and it is a medium grassy green creme.
