Color Schemes for the design of the companion of the main character for a personal project.
A sad and lonely girl who is traveling alone through an unreal, dreamlike, lonely world, her own inner world. She is accompanied by a small and robotic friend. Maybe she doesn't want to be that alone.
The second image is the chosen version.
