I’d guess that someone had the bright idea to automatically randomize the notes on the fridge every time, in order to avoid this problem: https://reelrundown.com/film-industry/Same-newspaper-prop-in-different-movies https://reelrundown.com/film-industry/Same-newspaper-prop-in...

Although I don't know what tool they used, probably it was something like this, where they created many instances of an object and used a random number function for the color. Whatever they used for the seed, it must have changed between shots, program reloads, users, or something else and I would suppose the artists either didn't notice or couldn't figure out how to fix it (I suppose you would just set the colors manually on each instance)

  I work in Blender quite frequently, I'd imagine this is the case. Many off-the-shelf assets behave this way.

Animation is a big complex process that involves a lot of hands with tight deadlines; "we changed some stuff in the process of revising a scene and did not re-render every other scene this change touched because of time constraints/human error" is probably a good theory for most continuity errors, though Teddyh's theory of "automatically randomize the magnet colors" sounds pretty plausible for this particular case. It sounds like something really easy to set up for the props once, on the expectation that they will never be more than background detail, then accidentally draw attention to with a closeup sequence animated by multiple animators. In general, animators will take any shortcut they think they can get away with. :)
