In Rooty Tooty Toot it has so many colors in the background like when the lady in blue was telling the court her witness the flashback shows the background blue (i think it means sad because the way she was singing or was the voice actor meant to voice it that way?) And when the bartender shares his witness his color was gray. I loved the patterns that the animators used in this short because it’s very detailed. Using both colors and details is effective because it does tell a story like when you’re using red it means anger and the details show what happens in the shot.
