That’s an amazing chart you have of everybody’s tomborita colors! Though would Victor and Carla’s tamborita colors have changed since they now practice good magic instead of dark magic?
Thank you! And about their magic colours, well we cannot truly know for certain. The only spells that we see them do after they switch to good magic is that sparkly flourish spell they cast along with Gabe and Mateo at the end of The Lightning Warrior, and the spell that Victor cast in the finale at Ash. For the first one, I don't think it really counts towards showing their true magic colour because some spells like Conglari are always the same colour no matter who casts them, and that was probably one of those kinds of spells (I mean none of them even had to say anything before they cast it so it was probably just for show). The spell that Victor does in Coronation Day is still that dark blue/purple colour that he normally uses (Although out of all the tamborita users his colour seems to be the one that fluctuates the most). But we never got to see Carla cast another spell so we can't really be sure whether it was just a coincidence or not.
In my personal opinion though, I headcannon that they stayed the same. I like to think that there aren't really any colours that truly mean good or evil. It’s how the person decides to use their own magic, whatever color it may be, that makes it good or evil.
