Bathed in blue

After seasons of ho-hum home spa color schemes -- white on white on white, with a touch of teak or green glass tile -- bathrooms are getting the royal treatment. Vibrant cobalts, refreshing turquoises or soft shades of sky blue add a Newport Beach neo-preppy splash to the powder room. On the vanity, the latest trend is translucent, glossy plastic and satin-finished resin accessories that work well with floral towels or the exuberant Italian patterns of Missoni.
