Sorry if I’ve not been up with recent discussions, but what was broken about Holdo’s hair being purple?
Though some may want to tackle it as a technical challenge / exercise (apparently it is quite a difficult, labour-intensive task to to do - and get right).
Others don’t like the Holdo character and wish to make changes to her.
An aesthetic choice - some seemingly don’t like (through to some not being able to stand) people having purple hair in their Star Wars space opera / fantasy films.
A few have problems that the purple hair meant that the Holdo character was a lesbian; an oft-mentioned comment when making racist, sexist, homophobic or other derogatory comments on other female characters in the Sequels too.
I like to think most on here doing this change for Edits see it as an aesthetic choice or a technical exercise / challenge…
