[Feature Request] Add feature to invert colours of a local pdf #2562

It would be really nice if the darkreader also inverts colours of pdf files local to the device similar to a feature of Adobe Reader

Exposed as 1 big element we can't touch any specific elements.

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);
}
