Is there a PDF reader and editor with dark mode and multi-color highlights?

The use cases are: A GOOD dark mode (if possible not only inverted colors). Highlights with different colors. Fill some tests (for example in questions where you have to put True or False, add comments or edit some parts of text). I achieve all of this with Adobe Pro but now I'm not in Win anymore, I hear suggestions.

Solution 1:

Okular has all these features. It also allows you to change the background color (not just invert it).

sudo apt install okular

It also allows one to fill up (non-XFA) forms.
