Since Kate Mara first popped up on the Hollywood scene (over a decade ago), she's never really strayed from her redhead hair color. She's sometimes opts for a darker auburn shade, but it's still pretty close to her natural tint.

But, as they say, there's a first time for everything. Over the weekend, the House of Cards actress was spotted strolling in West Hollywood with a newly blond hue.

Because her hair was slicked back—one of her signature styles—it is hard to tell the exact shade, but it appears to be a sort of dirty blond hue.
