Green is especially great in the bathroom - when paired with white, it looks fresh and clean. I love the multiple shades in this space, and the tiny tiles that give the wall an organic feel.
This kitchen, compared with the bathroom above, really shows off green's diversity. This pretty pale color sets a calm tone in the kitchen, so different from the intense energy of the bath. It's not boring, though - imagine the wall as beige or even blue. It wouldn't be nearly as interesting.
Another kitchen, another shade of green. I love how this teal works with the deep blue cabinets and blue and white floor. White accessories and fixtures keep the colors from looking too intense - the whole effect is really cool.
The walls don't have to be green for the color to take a leading role in room design. I love how these simple pendants energize an otherwise neutral space (without competing with the amazing windows). Green is the perfect choice here - it is much more fun than plain metal or a neutral, but not terribly limiting in terms of other design decisions. The owner of this kitchen could set the table using nearly any colors and the whole space would still look great.
One of my favorite things about green is how well it pairs with nearly every color. The green-orange combination - sometimes jarring at first - is one of my favorites. In fact, this picture is from my own kitchen - which, like most of my house, is painted green. (In this case, it's just about the same color as the Le Creuset pot.)
This softer version of the green-orange combo is perfect for a young person's bedroom. Green walls create a relaxing sleeping environment, especially when paired with a great view of nature, and a shot of orange makes it easy to wake up in the morning.
Combining green and red is a really bold and, I think, great color choice. Done without care, it can turn a room into Christmas central, but when offset by wood and natural light, it's really cool. Plus, in this room, the energy of the red door is boosted by the dynamism of the live green plants. It would be a great place to wake up, don't you think?
