Since brown doesn't have an opposite or complementary color on the color wheel, most eye makeup colors will work for women with brown eyes. Follow these simple makeup tips for brown-eyed gals to look your best and enhance your natural beauty. "Brown eyes are the one color that most eye shadow colors work well on, says SheKnows Beauty Expert Nina Sutton." "The determining factor is usually the depth of the eye color -- are they almost black, or are they medium brown?" Women with brown eyes can also pull off both black and brown eyeliner (brown works best in the day and black at night). 1. For deep brown eyes If your eyes are dark brown, medium to dark shades of eye shadow will work for you. Try plum, forest green or charcoal gray. Check out the flecks of lighter color in your eyes and use those hues to select your eyeliner color. "For darker brown eyes, also try dark browns or mauves," says Nina. "Gold and bronze is also beautiful on dark brown eyes." 2. For medium brown eyes "Medium to light brown eyes can try green, violet or bronze colored eye shadows," says Nina. You truly can wear almost any color of eye makeup if you have medium brown eyes. A purple or green eye shadow palette can work equally well for daytime. Experiment by pairing neutral shadow with metallic eyeliner in copper or bronze for evening. 3. For light brown eyes Avoid black eyeliner, if you have light brown eyes, use dark brown or other colors instead. Apply a neutral shade of shadow on the lid, a darker hue of the same color in the crease, then line your eyes in gold or green to reflect the flecks of color in your iris. If your eyes are so light they are hazel, try champagne tones with violet, bronze or brown liner to define the eye, offers Nina.
