Featured here are all the rough sketches, unused designs and colors tests me and Alpha2 did for our Rainbow Brite redesign project.
Final designs for Rainbow Brite and color kids: [link]
Final designs for Rainbow's supporting casts: [link]
Final designs for Rainbow's villains: [link]
Note: The characters on all 3 final pieces are set in the same ratio and scale. So if you ever want to put them on a single image, you will find them in the correct height to each other.
