The "how it should look to Kjorteo" version shows Rattle as bright neon lime green and Roll as magenta. Are you sure that's how it's supposed to look to me?

Anyway, I get #ff8e71 for Rattle, a sort of coral pink. Roll's portrait is #ca85ff, or "Kjorteo-colored," but the in-game sprite is a much bluer #a48aff.
