Ashlee Simpson [1] debuted a new hair colour that will completely transform your Halloween [2] beauty look: a smoky, peach-pink that her hairstylist called "Pumpkin Pink."

Riawna Capri, the mastermind behind the new pink hair colour [3], told POPSUGAR that she wasn't surprised the hue suited Simpson since, "[she] looks amazing in all shades of reds and coppers." To ensure her hair was strong and shiny postcolor, Capri made sure to use her salon's hydrating treatment, the Crystal Cashmere System.

Capri also posted a breakdown of how she created the look on Simpson in her Instagram post debuting the look, saying that she mixed ⅔ Rose Gold, ⅓ Bronze, and "a dash of" Blush from Joico's Colour Intensity line. She noted that this combination works if you're already have bright blond hair.
