This season, no less than eight dark green polishes landed on our desks (see our November story) and the experimenting began right away. We tried the black, shimmery greens, like OPI's Here Today...Aragon Tomorrow and NP2 Nail Perfection's Atomic; the intensely deep emeralds, like Envy, a shade name chosen by both Zoya and Hard Candy; and Barielle's bright olive shade, known as Polished Princess. 
Jamie's nails, in British Racing Green by Butter LondonAnd, oh, the comments we got! "Is that green you're wearing?" nearly everyone asked. Personally, I've preferred keeping the green to the toes, but my colleague Jamie has been experimenting with emerald-hued manicures. Her favorite is Butter London's British Racing Green. "It's a deep emerald that's vibrant without being too bright, and it has a glossy sheen that's not glittery," she explains, adding, "I found some of the muddier greens to be a little dull for tastes."
My favorite, meanwhile, is Orbis Non Sufficit by Rescue Beauty Lounge, which I love exactly for that so-called "muddiness" (I would describe it as "muted"). Notes our fashion department colleague Kathy Lee, another fan of the Rescue, "Since it has that gray undertone, it's a good neutral." That is, if green can be considered a neutral.
A lighter shade of green (more for spring): Chanel Nail Color in Jade, as seen in October's "Art and Commerce" portfolio by Inez van Lamsweerde and Vinoodh Matadin.
