The fundamentals of a smoky eye are simple
For a new twist on black, stroke on navy liner and top it with cream shadow in a similar shade, patting it in with your fingers for a lived-in effect.
Take a traditional color—like chocolate brown—but smudge it around your eyes in a modern oval shape.
Deep jewel-toned colors like amethyst impart a mysterious quality. Concentrate your application from the lash lines to the creases for the most impact.
Work your usual dark liner and shadow all around the eyes, but finish with a touch of sparkly platinum cream shadow in the inner corners for rich contrast.
Trace on two eye shadow shades—dark black closest to your lashes, metallic beige just above—and blur both past the outer corners for a double smoky-cat-eye look.
