From platinum blond to chestnut brown, Sienna Miller has spanned the spectrum of hair shades through the years, but now the 31-year-old actress is opting for a slightly less natural style.

While walking the red carpet at the 2013 British Fashion Awards on Monday, December 2, the Hippie Hippie Shake star played up her flowing locks with striking pink highlights.

Sienna’s always marched to the beat of her own drum when it comes to fashion and beauty, and the rose-gold style furthered amplified her bohemian sensibility. The British beauty paired the unique shade with an emerald green gown by Burberry and a sparkling bronze clutch. (So festive!)

“Gave Sienna a funki tint yesterday,” tweeted celeb stylist Alex Brownsell. “Pastelpeach #bfa #vpretty.”

Sienna’s not the only star Alex has treated to a Manic Panic style. The hair goddess can be credited with the fiery red locks of Florence Welch, the multi-hued strands of MIA, and the pale pink hair of Ellie Goulding.

Are you liking Sienna’s #pastelpeach style, or is natural best when it comes to the red carpet?
