Blue and GreenWhy it works: "The popularity of blue and green—colors that symbolize nature—reflects our renewed interest in the environment," Eckstut says. And while just about any blue-green duo works well, today's pairings tend toward brights—lime or grass green coupled with robin's egg blue or aqua, for instance. Can you say sharp?
Variations: Delft blue with lemon yellow, or light blue with a darker tone like turquoise and navy.
Easy idea: Soft blues and greens bring serenity to a bedroom, so introduce these hues into your boudoir with fabrics: Create a customized headboard—and a luxurious focal point—by hanging a swath of patterned silk or other dreamy fabric at the head of your bed, running it up the wall and a couple of feet onto the ceiling before letting the edge of the fabric cascade down. Finish the look with a mix of blue and green accent pillows and a crisp throw folded at the foot of your bed.
