Brown eyes look their best with shades of coral, copper, beige, pink, and brown.
(Blue or violet eyes are best set off with shades of blue, violet, gray, sliver, and kohl.
Green eyes look lovely with shades of coral, taupe, mossy green, gold, and brown.
Hazel eyes are a mix of brown with green and gold flecks, so you can use the same complimentary shades ideal for both brown and green eyes.)
Application
Although there are many ways to apply eye shadow to create different effects, following these general application guidelines should provide nice results.
Use a light shade of shadow under the brow line.
Apply a complimentary medium shade to the main lid, and use your finger to blend where the two colors meet.
Then, apply a third darker complimentary color along the crease in the lids to add depth. Be sure to blend it in with your fingertip.
