💡 Feature request: Custom accent color that persists between light/dark mode

[Tech-How]

Describe the feature you would like to be implemented

It would be nice if the user could select a custom accent color that would persist across light and dark themes. I prefer the older blue color for Redlib, but if I select one of those themes, then the website no longer automatically switches between light and dark mode depending on my system. (By time of day)

Describe alternatives you've considered

I can select either Libreddit Light or Libreddit Dark, but there is no "Libreddit Auto"

Would also get rid of this red accent color because red accent is very hard to read for me.

This is my feature request, that also respects your feature request #299
