Save a pdf with inverted colors? (lemmy.world)

Is there any way I can convert my PDF into a dark mode version without converting it into images first and invert that image and combine them, instead simply invert every element in the PDF and make it dark (preserving the original text and hyperlinks). appreciate any help!

I don’t remember where I got this, I just jotted it down in my notes.

gs -o inverted.pdf -sDEVICE=pdfwrite -c "{1 exch sub}{1 exch sub}{1 exch sub}{1 exch sub} setcolortransfer" -f original.pdf

Edit: this might well be the original post I found: https://stackoverflow.com/a/30287097
