The thing about colors is they’re so easy and efficient as symbols we don’t even consider them as deeper elements of storytelling. The connotations of the colors black and red are so pervasive and intuitive to an English speaker it’s hard to even imagine a version of My Immortal that doesn’t use them to convey the emo pop mall goffik sense of aethetics associated with the fic.
Nobody living in modern anglophone society, not even someone pretending to write like a concussed 12-year old, would accidentally dress their depressed vampire goth protagonist in yellow, beige and pink thinking those colors usually represent those character traits.
It’s fair enough to criticize that, but the curtains are blue meme makes a really bad argument. It would be one thing if the author said “the curtains are blue because the detective is colorblind and couldn’t see the bloodstains on the green curtains” or “the curtains are blue to represent Virgin Mary”. Ha ha the teacher was wrong, what a fool, blind leading the blind.
The meme actually implies that authors typically add utterly superfluous sentences in their stories and that it’s wrong to try and interpret them as if they’re connected to the rest of the story.
