We've all heard the warning that using more than one bold color in a room can overpower the space. But sometimes it's worth throwing caution to the wind. If you love the look of bright colors and have a few favorites you want to combine, go for it! Paint two accent walls, one in each hue, or opt for a bold color for the walls and a bright splash of color for linens and accents, like in this charming kids' room by Clean Design. As long as you achieve a sense of balance, there's no reason you shouldn't risk breaking this old-school rule.
