           Summary: Change colours so they are readable.
           Product: okular
           Version: unspecified
          Platform: Other

SUMMARY
***
I want to be able to change the colours without changing images in the files. I
can't handle bright white backgrounds, the accessibility options are limited. 

If you invert the colours, the embedded images are displayed in negative, this
is obviously wrong.

If you change the background to black, the text is also black, why is there no
option to change the text colour?
***


STEPS TO REPRODUCE
1. Open book
2. Change accessibility options
3. See result

OBSERVED RESULT

Inverted colours on images or invisible text.

EXPECTED RESULT

Text colour option and correct colours on images.
