Kate Mara turned up blonder than we remember to a private Dior luncheon yesterday. Typically, Kate wavers somewhere between chestnut brown and a deep auburn red, but now she is trying out a golden hue with darker roots. Her ends are teetering on bleach-blond territory, but she complemented her new hair color with a neutral makeup palette. It's clear we'll have no problem separating Kate from her dark-haired sister Rooney now, but what do you think of her lighter hair color?
