But it’s not as deep as in Xanthoria – I think lavender might be the word to describe it, but I’m not a master of the names when it comes to colors.

Yes, that’s my experience with KC test in this species, too

And it’s a distinctive purple, not the wine-red “purple” you get with Xanthoria for example. Almost a lavender or something like that instead, right?

KC+ displays purple color really briefly if I manage to put tiny amont of C on top of K. If I put entire drop, I guess it floods it and I can’t really see any changes.
