She was initially introduced alongside her sisters in Fallen Wings event on the Chinese server in December 2017. However, a conflict between Yostar and the artist that designed Colorado and her sisters had made the event delayed for other servers until October 2018 when another artist was commissioned to redesign her.
Eventually on October 2018, Yostar commissioned another artist, Chuzenji to redesign her. Under the redesign (post #3297428), Colorado and her sisters is now themed after gothic vampires. For Colorado, she now sports a long white hair. She still wears a sleeveless shirt albeit now in black and white and showing her sideboob, as well as a black coat.
