Light vs Dark: The Olsen twins display the power of lipstick. Photo: Michael Loccisano, Getty Images

Last night, The Olsen twins demonstrated the power of lipstick.

On the red carpet for MoMA's Second Annual Film Benefit, Honoring Tim Burton, Ashley paired nude lipstick with subtly smoky eyes, while the more daring Mary Kate opted for a bold, wine-tinged shade that's right on trend for fall and winter.

While both of their looks are gorgeous, since the Olsen twins are, well, twins, you can really see how different a bold versus natural lip makes you look.

Mary Kate's dark lipstick highlights the angles of her face, and makes her skin look pale for a very sophisticated look. Ashley's natural lip draws attention to her eyes, and helps her skin tone look more golden. Paired with tousled hair her look is very La Dolce Vita.
