Here's Essie's "Sew Psyched" from the Fall 2010 collection. The best way to describe it is just the way Essie does on their site "a cashmere-soft sage pewter". Since the color is a little odd I took pictures in different lighting so you can get a better idea of how it looks.
& here it is with some Konad from the m78 plate :)
Thanks for looking & Happy Lacquering!
PS: Just in case you haven't seen it yet, I added a tab that has my current nail polish inventory :) check it out! http://lacquerobsession.blogspot.com/p/inventory.html
