Pale green can transform a sterile white bathroom. The trick to incorporating color is to keep the accents crisp, not flowery. Otherwise it can feel like a minty-fresh throwback to the chintz-and-mauve days of the early &#39;90s. Art deco touches, like the patterned shower curtain and diamond tile trim, or a warm, neutral palette (think white, tan or silver accents) strike just the right balance.
