Here is a scene from Snow White, animated by Bill Tytla, in which four of the dwarfs fight Grumpy. The drawing above is the first of these drawings and it shows what it looked like in color – lots of red pencil notes, yellow pencil for rough structural lines. The rest of the drawings I have are B&W copies.
By the way, if you like this material check out Hans Perk ‘s site today. It deals with forces vs. forms in animation. This is what Tytla was all about in animating.
