Ever since she was Princess Buttercup, Robin Wright Penn has been known for her enviable caramel blond hair. Yesterday, though, she arrived at a screening of The Private Lives of Pippa Lee with dramatic espresso hair and a much sexier look (she's also aging fantastically, don't you think?). I love both shades and I admire her willingness to go for a big change, but which color do you think suits the Princess Bride better?

Which Hair Color Do You Prefer on Robin Wright Penn?
