Is it possible to add dark theme in Document Viewer?

[Istiakshovon]

I usually use Document viewer to read PDF files. But, white color affects eye. So that I am thinking to add dark theme to Document viewer. I searched in Internet to get dark theme but, didn’t find any way to add dark theme to Document Viewer

In general, program theme is dependent on your system theme, that setting you can change in your system settings.

You are looking for a dark mode not a dark theme if I understand you correctly.
There are options to read PDF’s in darkmode.

Have you forgotten already?

Why I can't use dark theme in Manjaro?

Unselect automatic dark theme in Layouts , and try choosing a dark theme in extension User themes and in Gnome Tweaks.

@Tomek You got me wrong. I am looking to change my system theme. I am thinking to change theme of Document Viewer.

@Yochanan No! I didn’t forget.

@Hanzel Thanks! It was helpful.
