One of the biggest myths in interior design is that dark wall colours make a room feel small. While it certainly makes a room feel more intimate and atmospheric, it can, ironically, even make the room appear larger than it really is. The reason for this is that a dark colour makes the walls "recede" from view so you're less aware of the room boundaries. For trend conscious homemakers, try a mossy Hunters Green, it's bound to make up next season's palette du jour. For a colour with can't-fail-longevity, opt for a Charcoal grey with a brown undertone instead of the customary blue.
