I learned a great trick from The Makeup Diaries for how to keep smokey eye makeup from looking too heavy. After you get all the dark colors on your lids and blended to perfection, take a light peach eye shadow or blush and sweep it very lightly along the crease (that spot on your lid where you can feel the top of your eyeball). It'll be so incredibly subtle that you might not think it's making a difference. But trust me - especially in photographs, the effect is great. Your eyes will look a little brighter and lifted.
Another way to make use of peach to appear more awake is with a nude or beige eye pencil. Once you've got all your makeup on, swipe a bit of nude pencil along your lower lash line and in the corners of your eyes (near the tear duct). Again, the look is very subtle but effective.
Two products I like for these tricks are Sephora brand Nano Eyeliner in Pure Beige (09), and Benefit Georgia blush.
