For the most part, I really enjoy the Dark UI theme. However, when viewing documents that include images or other colored elements (like certain PowerPoints converted to PDF), the color inversion in the document reader in any theme other than White can really throw a wrench in my workflow.
Attaching an example image. Notice how in the dark theme, the color-coding in the document picture is useless.
The option to choose whether or not the document/images in the document reader get their color changed would be much appreciated.
