If you're a new brunette (like Cameron Diaz many a time) Taylor Chang Babaian, the celebrity makeup artist behind Style Eyes, says to be sure your makeup contrasts with your skin. "Add pops of color so you don't get lost in all that hair."
But as opposed to playing up one feature, try to harmonize your eyes, cheeks, and lips. Go for gold and bronze shadows to reflect your new hair color and illuminate your eyes, while using a pink and peach blend on the cheeks and a neutral mauve on the lips.
