I agree with other commenters about the need for this feature. I work extensively with digitised copies of old (19th and early 20th century) magazines, so the whole document is made up of page images. I also have a visual impairment that makes it difficult to work with white screens and have been busily implementing dark mode wherever I can on my devices. It would be great to be able to invert the colours to white print on black background.
The absurd thing is that you can do this (i.e. display a PDF including images with colours inverted) in Acrobat Reader for Android, but not for the Windows version. Why the difference?

I need this feature as well due to my visual impairment.

In addition, my staff. that spends hours a day reading documents by computer, would find this feature useful -- working long hours with very bright white backgrounds causes eye strain and headaches.

This is a highly sought after feature. I work in UX design and a lot of customers are asking for the same. The need is to be able to over-impose High Contrast colors on top of images embedded in PDFs and also on PDF documents scanned as image. Customers are looking for true High Contrast functionality that works in all scenarios and not just for text-based PDFs.

I have been using okular in linux for somedays and it also has a windows version. I have found a really great feature named "Change dark and light color" which enables the user to change the colors of different color value of the pdf(scanned or not), which is very helpful for readers with dark mode. I have searched about this feature and found this https://answers.acrobatusers.com/changing-background-in-scanned-document-q88322.aspx

. I think this doesn't work simply and takes much time in my computer, moreover it is not so useful as okular's is, also figures in the pdf which are lost. Please add this feature to this app.

I'm visually impaired and find anything with a white background impossible to work with. I use Windows High Contrast mode to force a black background for most documents. For Acrobat PDF files, this does not work with documents that are scanned as images; these retain their original colors (white background/black text). I work with multi-page electronic faxes where every page in the PDF file is a scanned image displaying as white background/black text. Since I can't change the settings on scanner/fax for how these files are saved, it would be helpful if Adobe could add an accessibility option for inverting the colors of documents scanned as images.

(Note: Adobe's built-in High Contrast options in under Edit>Preferences>Accessibility do not work with scans of this nature either.)

Thank you for your suggestion Rachit. That method does achieve the desired result on images in pdf files but is very detrimental to my selection of high contrast colour settings used throughout Windows.

Please can you add an accessibility option to invert colours in images embedded in pdf files.
