wally is a living hue shift. His watch, being a live projector monitor with a simple click. Helps him identify colors on things, with a simple tap. However, sometimes. The colour can be mixed up, and he can be given the wrong one sometimes. Causing his hair to change from a ocean blue, to a cherry red. Like emotions. He also has pink hair, for when hes deeply in love/lovesick. A deep purple and blue, for panicked. And a deep blue, for sad. His tie and shirt also change color on his emotions.
