It's funny; I have a pretty extreme night light filter (i.e. blue is almost completely removed) and even through that it at best looks.. maybe gray and black?
Then when i turn the filter off it just becomes hilariously obviously blue. Like.. It's blue: you can tell by the way blue light is hitting the retina 🤯. At most i could stretch myself to consider it purple-ish, but that's just blue with some red mixed in..

But yeah i can theoretically understand thinking the black is golden, though even then it's just not quite right for me to ever see it. Like if the light was significantly exaggerated THEN i could probably force my brain into considering the black parts to genuinely be at least dark gold material.
