At first I was really happy about the new dark mode that colors the page black. But it is not that good to use in my experience, so I want to use a dark UI but white / light page. This seems to not be possible. I have added the "toggle dark and light mode" button to my toolbar, as otherwise whenever starting Libreoffice, my toolbar is white and the icons are also white. I go to settings and set the light theme, which does not apply to the toolbar. This might be a bug but it currently makes it usable for me. Applying the color to the document background only is not possible, as the button is greyed out. I think when I set one, it didnt work anyways and stayed black. There might be multiple issues, one is that the UI does not reload the color scheme, the other is that something seems to block me from changing the page background color.

okay it seems I need to add a custom theme and set the colors there. If a default theme is used, the button is greyed out.
Glad you got it working. You also could try installing one of the Appearance theme "extensions" (the puzzle piece icon). Any of the Light Application Colors, Lime Theme, Office 2003 Blue, or Dark Gray flavors. Note: it is a bit of nuisance to fully remove an applied appearance theme and revert back to default Automatic theme, but that is being worked on for 25.8 release. Meanwhile, the Theme designers are building the Appearance themes with color definitions for both a Light and a Dark color schemes. The colors will follow what mode the os/DE indicates, so called 'System' color. Alternatively, on the Tools -> Options -> Appearance panel there is a 'Light' and a 'Dark' radio button that will after restart force the theme to use that set of colors from the theme regardless of what the os/DE reports. These themes can be modified, or saved as template to a new theme of your own naming that you can further modify.
do you know if I can extract a theme? Because it is currently not possible to clone a theme and then edit it. This would be best, as all themes are still buggy in the "add header bar" hover button which is not readable. The breeze dark theme works, but I can't clone and edit it.
You clone the current theme (default Automatic, or an Extension theme) by clicking the 'New' button and giving it a name. It gets written into your LO per user profile. In that new theme, the 'Customization' list box will allow you to choose specific UI elements to adjust in the cloned theme. You likely will want to incrementally test the combinations, the 'Apply' button will set some of the color immediately but some will require 'Restart' of LibreOffice to assert. Specific UI elements to adjust is up to you as your own theme designer. But maybe start with: Document Background Font Color Window Color Take notes and figure what works to your liking. Maybe download and install a few of the theme Extensions. Their .OXT can be opened in a Zip viewer and you can review the colors (unfortunately RGB colors are in decimal rather than HEX triplets) At 25.2 you will probably need to delete profile to get back to default os/DE Automatic colors for the Automatic profile should you end up with any colors set by Light/Dark mode toggle. For 25.8 the 'Reset' button should reapply the default os/DE colors, but require a restart. If you get further into designing color schemes there is a macro to aid with picking the colors for the entire theme and converting them from hex RGB to decimal RGB notation needed for the themes. Have fun, post BZ issues, and look for better theme handling at the 25.8 release.
true, the theme inherits the dark or light defaults. sorry, I was wrong and it works really well
