Red Soul mode is reffered buy wiki as "normal mode", but then why are other souls different color? Were they turned that way by the monster who ended them for good (I personally doubt that is the case, but it's a little thing that came to my mind)?

I also have a theory that Red mode is a boss monster's mode(Toriel, Asgore, Asriel) because powerful monsters seem to have color mode abilities...
