Okular How to change colour of Hyperlinks? Links extremely dim / light colour color hard to see

Hi all.
In Okular:
Hyperlinks are EXTREMELY dim, a very light colour, and difficult / almost impossible to see.
No matter what options I choose, the colour is very similar to the page colour.

Example:

On a white page, hyperlinks are a very light grey colour, almost white.
When I “Change Dark and Light Colours” under accessibility settings, hyperlinks are almost the colour of the page, no matter what colours I pick for dark and light.

Things I have tried to change the colour of hyperlinks:

  • Changing “Settings > Colour Scheme” to any/all of the various options. No effect.
  • Switching options under: “Settings > Configure Okular > Accessibility”. My preferred default setting here is “Change Dark and Light Colours”, but it doesn’t matter what option I pick. The hyperlinks are almos the colour of the background.
  • I have examined the 2 okularrc configuration files under .config, and cannot see anything relevant in these.

When I have Okular colour settings set to default, the hyperlinks are an extremely light grey, almost the colour of the white page.
When I am in dark modes, the hyperlinks are almos the colour of the black page.

This is a fresh install of a debian fork. I am using the settings I always use (I think), and it is the first time I have encountered this problem.

Apologies if this has been answered before. I had a look around the internet, and searched these forums. Couldn’t find an answer.

Thanks!

I suppose the setting could be under ~/.config/okularpartrc

but if so: I am not sure what to modify. I have tried plugging any of the hex values at the bottom of that file into a colour picker, but the colour picker doesn’t show any of the colours I am seeing for hyperlinks in Okular.

Any help would be greatly appreciated, as this is hindering my ability to study and write documents at the moment.

Thank you in advance for any help.

I guess there must be a lot of other issues to solve, but is there really no simple fix for this? It makes Okular very difficult/annoying to use for any document containing hyperlinks.
