This room is a showcase for the great combination of green and gold. The addition of the black in the rug, painting, window coverings and accessories give the eye a place to rest in a visually vibrant room.
When using a bold pattern or color such as emerald green, I always like to repeat it somewhere in the room so it looks deliberate and cohesive. In the above photo the decorator added pattern and color in the drapes and repeated the color in the artwork above the sofa and with the chair.
Another successful way to work with emerald (or any bold color) is to temperate it with cream and white. By adding the color through accents such as a throw or toss cushions - instead of committing to an expensive purchase such as a sofa, when the color trends change, you can keep up without a lot of work or cost.
Although emerald is certainly another bold color of the year I don't believe it is as polarizing as 2011 choice of honeysuckle. Emerald is also a color that plays well with others such as gold, fuchsia, yellow, navy, and brown.
How have you decorated with emerald? How do you incorporate on trend colors into your decorating?
