Still looking for that silver bullet that makes you appear well rested when you're not? As it turns out, a bold blue, green, or purple liner can do the trick, giving you just a touch of eye-brightening tint. Use the colored pencil to trace the inner third of your lash line, top and bottom. Line the rest with brown or black for balance, then brush on a neutral shadow.
