We’re used to seeing Sienna Miller as a cool-toned blonde, but just in time for winter, Miller has changed things up. Miller, who revealed her new look while out in New York City, stepped out with her signature blonde hairdo looking much darker—almost coming across as a brunette.

The caramel color seamlessly transitions her summery hue into the upcoming colder season and easily blends her highlights throughout the mid-lengths to prevent the need for constant touch ups.

As a bonus, the darker color isn’t as harsh on the hair during the dye process and is much more low-maintenance than brighter shades. As a non-damaging way to reboot your hair color for winter, we can’t help but think quite a few other celebrities will soon follow Miller's example.
