I kinda like the idea of a First Kill reboot where Calliope is a goth girl and wears a lot of black while Juliette is preppier and wears brighter colors because it would subvert expectations regarding the usual designs of vampire and human characters. It would also make sense because Juliette and her family try to blend in amongst humans while Calliope might feel a bit like an outsider due to her being part of a family of vampire hunters!
They’d basically be this meme when they’d see each other for the first time :
