According to Allure, good eyeshadow colors for women with dark brown eyes include bright blue, green, copper and gold tones. Shades of navy blue are also a good choice.
Brown is a mixture of all of the primary colors, so many eyeshadow options complement dark brown eyes. Bright blues in cobalt or sapphire shades contrast well against brown and make the eyes pop. Green tones, whether in metallic or matte shades, pick up brown flecks in the eyes. Copper eyeshadows add texture and warmth to brown eyes, while gold shades bring out gold undertones in dark brown eyes. Allure suggests using navy blue to create a noticeable contrast that is a perfect look for daytime.
