If you use Firefox, you can edit userContent.css like this:

@media (prefers-color-scheme: dark){
  .pdfViewer{filter: invert(1) hue-rotate(180deg);}
}

If you use Chrome or Edge, install the extention "PDF Reader", then edit the extention option like this:

html[data-theme*="dark"] .pdfViewer{
  filter: invert(1) hue-rotate(180deg);
}

@luo-chuan thank you so much! I've switched to Firefox since a few months, but I was unaware of the userContent.css trick. I love how customizable Firefox is
