Martha Stewart is an icon, an entrepreneur, a skincare mogul—and our unlikeliest new source of hair color inspiration for summer. She paired the rosé hue with matching eyeshadow and blush, and a glossy pink lip, leaning into a monochrome hair-and-makeup vibe. After all, there is no age limit on having fun with your hair and makeup. For the curious, Appleton shared his exact formula for getting Stewart’s new hair color in his Instagram caption. “For a rose gold formula, hi-lights BlondeMe 9+ 20vol, all lover gloss 9.5-19, and 9.5-5 rose gold base, clear 0-00,” writes the celebrity hairstylist.
