...Didn't Vax-kun mention something like that when he went to the music store? He saw a vision of two people fighting, and one of them saying the other's color was off? And that it had to do with someone dying?

[sounds like.... someone dealing with refraction to him, perhaps]

They saw a different color that didn't make sense to them. So maybe there is something off with your colors when you're refracted.

[this is so much thinking, hm]

...But even if we saw it, then could we do something in time to help them? Do they get refracted after they kill? Or when they wake up Thursday night?
