What Color Lipstick Looks Best on Gwen?

Gwen Stefani has a fabulous voice, a flair for fashion and a fondness for bright lips. On a typical day, you'll see her in some form of red lipstick (I even saw her jogging once with her painted lips on) but here we see her wearing a variety of shades. My favorite is the light pink because it really shows a soft and sweet looking side to her, but I know she can't rock that forever. What color lipstick do you think looks best on her?
