Blue eyes are actually one of favorite eye colors, since I too have blue eyes! To specifically make your eyes dramatically bold, I suggest colors such ash browns, greys, golds, rusty peaches or plums. As we know, metallics are hot right now and they are easy to use alone. Just apply them to the lid and crease.
Here are some product suggestions for you blue-eyed girls:
For a smoky quad, try Stila Smoky Eye Talking Palette in The Platinums, $40. And yes, it does have a recording in the shadow to talk you personally through your makeup application!
Be sure to check out these duos as well! I love my bargains!
MAC Cosmetics Mineralize Eye Duos, $19.50 in: Fresh Green Mix, Play on Plums, Under Your Spell, and Mayhem
One quick way of achieving a stunning, and light smoky look:
on the entire eyelid and into your crease but keep a light hand, then you can apply more if need be.
2. Then apply your highlight shadow under your brow and blend the two shades together just in that crease to soften the look.
Have fun with your show stopping new looks!
