Basically, I want a viewer which has a night mode or a dark mode so that I can change a pdf with a white background and black text to a dark background and light coloured text.

This method is only for text only documents. Otherwise the image colors will be inverted.
You can install Evince document viewer from this link and open it.Then goto the options on the top right corner as seen in the picture.
Then select Inverted colors. This will help you to read white text on a black background. In Evince document viewer 3.30.1+ select Night Mode.
Simply inverting colors doesn't provide the best readability (being limited to very bright white text on very dark black background), although it can improve it a lot in a dark environment.
Evince and also pdfstudioviewer can do that, which will result in something like this (in both image and text pdfs):
PDF readers that can change both page and text color in both text and image (scanned text) pdf files are:
Okular (in newer versions, like 1.9.3). See below.
Master PDF Editor More details in this answer, also
Zathura - as described in this answer.
I think this is more readable:
UPDATE on Okular:
In newer versions of Okular (like 1.9.3) both font and page colors can be edited — and a dark-mode look can be enabled — through a new and rather non-intuitive setting, under Configure Okular - Accessibility - Color mode: Change Dark and Light Colors, by selecting a light color for dark and a dark one for light color option.
Then, for easy access, configure toolbar and add Toggle change color. It works for picture/scanned pages too.
Adobe Reader 9, which can still be used in Linux, can change both text and background color but only in text-based pdf files. More here.
See my linked answer on Foxit Reader, which can match Adobe Reader but has no dark GUI and no full-screen.
Calibre Ebook Reader (like many ebook readers) can edit colors of font and page, but it can also open text-based pdfs.
Atril from MATE DE also has Inverted Colors mode (accessible with Ctrl+I):
You can install Atril with
sudo apt-get install atril
.I recommend you to go for Okular, one of the best readers for Linux platform. It is free of cost and provides features such as
I found all these answer are usefull then finally found this
This inverts all the screen , everywhere. So no need to find if a particular software have this feature or not. I can set a hotkey and now whenever I want dark mode I just need to press the Hotkey, works even for browser.
Installation
how about Foxit Reader? ( a big name on Windows - although the Linux version seems like minimal version )
It allows us to view a PDF in many better ways than Inverted Colors so you can choose what is suit for you ( and your eyes)

After testing through many pdf readers, I found qpdfview is the best application for viewing pdf in dark mode.
Foxit is the best in term of dark mode colors configuration, but it can't view djvu, there's no dark theme for the UI.
Here is my qpdfview's setup for dark mode, it should work for scanned pdf/djvu, and vector pdf.
<Invert colors> option ensures that scanned documents and images (which almost are in light colors) are in dark mode. When using <Invert colors> option, the paper color and background color should be light colors, such as:
Here is the result:
Vector pdf, with colored texts 1
Scanned djvu 2
If you're using Compiz WM with "Color filter" plugin installed, you can enable any of several nightmode filters for any windows.
i was searching for X software too and i could not find one my bad solution...using vim with a plugin ( Plug 'makerj/vim-pdf') let you do it just make sure your terminal is readable and you book as no real image and your set here a link to the "plugin" https://github.com/makerj/vim-pdf
WPS Office 11
WPS Office since v11 has a PDF viewer with Dark mode that works quite well (i.e. not just simple colour inverting). It also has Sepia and Eye Protection mode.
You can install it from:
