A colorscript is a sequence of small pastel drawings or paintings used to emphasize color in each scene and establish a film's visual language.

A car lost on a lonely road. A racer outcast within a packed stadium. Many key emotional scenes of Cars took place at night. Creating the paintings to define the lighting provided an interesting challenge. “Light is fictional at night,” explained production designer Bill Cone. Light sources that could illuminate the scene had to be invented and manipulated just enough to allow the audience to see what was important, and yet still produce colors that stayed true to a scene's mood.
