Creation and development of Rainbow Brite for Hallmark Cards is credited to both Hallmark's Vice President of Creative/Licensing Garry Glissmeyer, and a team of artists headed by Cheryl Cozad, and writers under the direction of Hallmark's Editorial Director Dan Drake. Hallmark's Vice President of Sales and Marketing, Lanny Julian, assembled a team of legal, marketing and public relations associates for this new licensing division.

Glissmeyer and Julian were tasked with breaking Hallmark into the licensing business with the creation of characters targeted at children. Glissmeyer's group's concept of a young girl with powers over nature evolved into her being responsible for all of the colors of the universe. Once the concept was agreed to, Cozad's and Drake's teams developed the backstory and characters needed to support it. Jim McDowell, a key player from Hallmark's marketing unit conceptualized a strategy to get the new brand in the public eye.
