Black girls can wear blue eyeshadow with the Indigo Smokey Eye Look. Purple and Dark Indigo and Navy Blue are very, very hot for fall.
How To Create Indigo Smokey Eyes
1. First line your inner rims of your lower lash lines with a black eye pencil.
2. Carefully line your lower lash lines with a purple eye shadow using a small brush. Then apply the same shade across your lids, blending the color up and over your creases.
3. Brush an iridescent blue shadow over the centers of your lids, and blend it up to just above your creases.
4. Finish your look by swiping back mascara on your top and bottom lashes. For sexy Indigo cat eyes extend your top like outward and upward.
