Cranberry and burgundy tones offer a striking color contrast against brown eyes, bringing out their warmth and luminosity. Apply a soft peach transition shade high into the crease toward the brow bone. Pack a rich matte burgundy shadow into the outer V corner of the eye and sweep it through the crease line using a tapered blending brush to build depth. Press a metallic cranberry or deep ruby shimmer shadow across the inner two-thirds of the eyelid, blending it gently into the burgundy outer corner. Line the tightline and waterline with a waterproof black gel liner to add intensity. Finish by applying generous coats of volumizing black mascara to emphasize the warm red and brown contrast.
