The Key to Finding Your Power Color? Just Ask Kate Middleton

Shortly following their ski trip to the French Alps, Kate Middleton and Prince William are back on the job, dressed with a whole new season in mind: Spring. This isn't the first time the duchess has zipped into her kelly-green Erdem jacket, but she definitely chose the right moment for an outfit repeat.

Lately, Kate's been showing off her glow in green, the shades of her designs gradually getting lighter as the weather gets warmer. For a trip to St. Thomas Hospital in London, where Kate and William visited mental health patients, the duchess accessorized her look with the classics: her Mulberry clutch, sapphire engagement ring, and standard black pumps.

While Kate later slipped off her coat to reveal a bird-printed dress, we had all eyes on the modern details of her outerwear, including its casual zipper and crisp collar. Read on to see why we're all for Kate giving up blue for this fresh new power color, then shop her look.
