You Can Do:
I can't find shades for medium skin.
Olive skin like Emmanuelle Chriqui's can handle a bit more pigment and warmth. Guerlain's Terracotta Light ($50; sephora.com) with multiple tones is your best bet, as it will add dimension to your face and prevent the color from appearing flat. A formula with flecks of golds and apricots brings out the natural warmth in your skin. Use your finger to dab on extra gold to the tops of cheekbones.
