Emerald fits from a psychological standpoint, too. It is said to enhance a sense of well-being and promote balance and harmony. It's also the color of growth, renewal and prosperity.

Making it work

But it can be difficult at times to distinguish emerald from other lush greens with blue undertones. Because emerald is a stone and a stone is faceted, it isn't always one definitive color, Eiseman said. It's a variety of shades.

That's what shoppers may discover when they go in search of emerald-hued clothing, accessories, eye shadow and nail polish.

What they'll also find is that the color is flattering to all skin tones and eye colors, and is striking on a dress, a set of bangles or the eyes.

Alex Mendez-Kelley, owner of The MakeUp Bar, said she likes green eye shadow, but she cautions moderation and choosing a complementary shade.

“You don't want to get a green that is too yellow and makes you look under the weather. Plenty of that going as it is, but a deep emerald eye shadow is sultry and elegant,” she said.

Not ready to embrace emerald wholeheartedly? Try a pop of eyeliner.

“Green looks great with taupes and bronzes as well as charcoals. I'm glad to see such a salt-of-the-earth color be our color this year. We are naturally drawn to it because it feels comfy. Who couldn't use a little comfort?”
