Brown eyes stand out with an eye shadow in a contrasting color, such as teal or deep blue. The shade of brown can be further highlighted by choosing a copper- or eggplant-colored eye shadow.
To make brown eyes appear to glow, use a copper eye shadow with an orange undertone, or choose an eggplant-colored eye shadow with a reddish undertone. These colors emphasize the eyes' depth of color. Using an eye shadow in deep blue or teal green creates a contrast, making the eye color appear deeper. To bring out the warmth in brown eyes, use a cool-toned silver or grey eye shadow. If an all-over lid color is too heavy, these color choices also work well for eyeliner.
