my protagonist has been in a "dimly lit room" for six chapters and I just noticed

I don't know when it started

chapter 4 maybee, she walked into a dimly lit room and something about it just felt right so I kept it. chapter 5, dimly lit. chapter 6, dimly lit. chapter 7 I wrote "the room was dim" like I was trying to be subtle about it

my character has not seen proper lighting in 30,000 words lol

I went back and checked and apparently every important conversation,emotional moment, confrontation in my entire second act happens in near darkness. My story should be subtitled "a woman and her issues, somewhere with bad electricity"

the worst part is I kind of don't want to fix it now like what if the dimness is load bearing. what if my whole second act only works because nobody can see properly

has anyone else accidentally given their story an aesthetic they didn't plan. because I think mine is just PERPETUAL DUSK
