Asian thriller about a young girl in a teen or y/a camp

sort of similar vibe to squid game, but different. probably came out late 2010s. dystopian authoritarian camp. main character is a teen girl. I think everyone in the camp place is relatively young. the camp place is very modern. colour red is a key theme - I’m pretty sure everyone wore red jumpsuits and there was a scene where everyone had to stand in rows and certain people got red paint poured on them. I think it was an asian film but I could be wrong.

Not an asian film, but “The Darkest Minds”?
