The color green has much to recommend it. As a cooler color, green helps to make a space appear bigger when it's used to decorate a room. It's thought to have a calming, and even healing, effect. And this nature-based hue is associated with rebirth — perfect for Spring. Whether you're determined to paint a room green in your house, or you're still on the fence, these shades — from mint and sage to evergreen and in between — may make you head to the paint store this weekend.
