Mean & Green has a murky blackened olive base color with green and purple sparkle/micro-glitter. It has a duochrome, so it flashes from pink-purple to olive-green. This shade was originally released with Venomous Villains (which is the bottle I swatched here), and it has since been added to the permanent range. It wasn’t quite opaque after two coats. Orly Space Cadet is exactly the same.
