ELI5: Why do thing that get moved or destroyed in older animated movies have a different colour (ex: you know a rock is gonna get destroyed because it has a different color than other rocks)

It's because objects that were to be animated in some way (as opposed to the backgrounds, which are fixed or just scroll around) were drawn and painted in a separate process, at a different time and by different people to the backgrounds. So their colors, detail level, and sometimes the art style didn't match the backgrounds perfectly - so you end up with that rock that you just know Wile E Coyote is going break with his head.
