Color Club Editorial Nail Lacquer ($8.00 for 0.50 fl. oz.) is described as a "peridot duochrome." It's a yellowy, dirty gold with brown and green in it that flashes from gold to grass green. It is, not surprisingly, a dupe for Chanel Peridot. The also recently-released China Glaze Rare & Radiant is rather similar as well (to be reviewed). Ozotic #507 is a bit darker, more green to blue than gold to green.
