Earlier today, Pantone announced the color of the year for 2013. Emerald will be replaceing Tangerine as the "It" color. Somewhat a coincidence too, with the new Wizard of Oz prequal "Oz: The Great and Powerful" coming out in the year of emerald. From the press release: 

Most often associated with brilliant, precious gemstones, the perception of Emerald is sophisticated and luxurious. Since antiquity, this luminous, magnificent hue has been the color of beauty and new life in many cultures and religions. It’s also the color of growth, renewal and prosperity – no other color conveys regeneration more than green. For centuries, many countries have chosen green to represent healing and unity.

“Green is the most abundant hue in nature – the human eye sees more green than any other color in the spectrum,” said Leatrice Eiseman, executive director of the Pantone Color Institute®. “As it has throughout history, multifaceted Emerald continues to sparkle and fascinate. Symbolically, Emerald brings a sense of clarity, renewal and rejuvenation, which is so important in today’s complex world. This powerful and universally appealing tone translates easily to both fashion and home interiors.”

So when you start seeing more green everywhere, that's why. I'm not complaining, green just happens to be my favorite color!
