Color can tell a story. To elicit psychological reactions. To draw focus to significant details. To set the tone of a scene. As well as representing character traits.

This photo presents a blend of cool colors inside the helmet and warmer colors outside. I would suggest that the colors above relate to the character's traits. A wish for more. A wish to escape. A brightness of personality. The characters true identity, intentions, thoughts, and feelings are completely hidden from the viewer.
