Rumer Willis just debuted a new hair colour [1], and she looks nearly unrecognisable. The actress revealed a warm copper colour [2] via Instagram on June 23, and according to the photo's caption, the change was inspired by a few legendary redheads.

Alongside a selfie of her all-new look, Willis shared a few mood-board pics of the classic witchy film characters and actresses she was hoping to model her cut and colour — done by colourist Amber Maynard Bolt [3] and Adir Abergel [4] — after. Among them was Susan Sarandon's character Jane in The Witches of Eastwick and Nicole Kidman [5]'s Gillian from Practical Magic.

"Was going for a mix of the Owens sisters from the marvelous mind of my favourite writer @ahoffmanwriter [6]," she wrote in the caption. "With a hint of Susan Sarandon in Witches of Eastwick and Thelma and Lousie [sic]." She noted at the end that she was also inspired by Julia Roberts's hair colour [7] in Pretty Woman, though she didn't include a photo of her in the gallery.

Willis is one of many celebrities who've made the switch to red, rusty colours [8] in the last few months, and she certainly isn't the only one who was inspired by TV and film characters. Gigi Hadid, for example, put the "code red" hair-colour trend [9] on our radar when she revealed in an Instagram Story back in March that she had dyed her hair after binging The Queen's Gambit [10]. Other actresses like Sarah Hyland [11] have also switched to the colour, and while Willis may have gotten in on the trend a little later, we definitely don't think she'll be the last.
