LET YOUR TRUE COLORS SHINE: Rainbow High is the leading global fashion doll brand and hit animated YouTube series that encourages creativity, celebrates diversity, and embraces inclusivity — each and every day. Together, with their friends at Shadow High, they’re showing the world that you should be proud to let your true colors shine. The Madison Twins are representative of both of these inspiring schools. While they love to express their unique personalities through their one-of-a-kind styles, they will always share and love expressing their love of the arts.
