Blue sits directly across from orange and red on the wheel, meaning those hues complement each other. So if you're looking to make your cerulean gaze take center stage, bust out orange-tinged, pinky-red shades, whether they're swept on eyes, cheeks, or lips. Salmon is an ideal pick because it's a perfect mix of orange and pink. Try MAC Lip and Cheek Color in Out for Fun ($20) for a natural glow that gives beautiful blues bottomless depth.
