While the color's name, smoky quartz, may not be a thing just yet, we're guessing that Emma's celeb clout may be just the motivation for girls everywhere to go darker for spring. Plus, Emma's known for changing things up in the hair0-color department, having been blonde most recently, but also red and brunette in the past — in addition to some more unexpected shades . Ahem, "desert rose?" Let's just say colorists like to get creative with their nomenclature. It was only a matter of time before she went with something new, and this gray-tinged brown is definitely fresh. All the transformations came courtesy of Nine Zero One, of course.
