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.

There were three ways to think of color in A Bug’s Life, says colorscript creator Bill Cone: What season is it? What time of day is it? And what does the story require—gloom, sunshine, or threatening shadows? From glowing mushrooms and shafts of daylight in the ant’s bunker to the late afternoon lighting scheme for Flik and Atta’s romantic encounters,
the colorscript set the tone.
