Have dark brown eyes and hair? Go for the chocolate! You're one of the lucky ones that can handle dark, rich walls. You can also handle bold color choices such as reds & oranges & bright yellows. These colors will compliment your dark features.
Blue-eyed? Try grays, blues & aquas. They'll make your eyes stand out & look clear.
