Ok, this would be very tricky and probably never going to happen…
Still, I’m leaving this in Brainstorm if someone ever gets interested.
Currently Okular has a built-in dark mode (which is badly hidden, idk why) that can be enabled in the Preferences. However, it would nice to have a dark mode which:
- Preserves images as it is
- Light text on dark grey background
- Colours are calculated, not just inverted, i.e., green stays green, even in dark mode, but a different shade of green to align with the dark background.
