Color Scheme not fully inherited across system

My plasma style is set to follow the color scheme, but about half the time, KDE partially fails and only the ‘Settings’ windows change color scheme as expected.

Here’s an example screenshot:

System Window: Successfully in dark mode
Task bar: Still in light mode
Application Launcher: Still in light mode
Chromium Extension that triggers via system dark mode: Still in light mode

Curious if anyone has an advice? AFAIK, the following variables aren’t the issue, but worth mentioning just in case:

  1. I’m using a Nvidia driver on X11
  2. I run a script that uses plasma-apply-colorscheme to change the color scheme instead of the GUI. (If/when the switch doesn’t occur via the script, manually editing the color scheme fails as well)
  3. The dark themes I’m using are Dracula/DraculaPurple

The only solution atm would be to log out and in again AFAIK (or to restart all the affected Plasma stuff and programs).

Currently, I use the following command:
killall plasmashell ; kstart plasmashell &

Is there an option that is less impactful to my workflow or should I stick to that?

For GTK apps, I simply stop then restart GTK synchronization service

Question, how often do you change your color scheme? You make it sound like you need to do this several times a day.

I haven’t changed my color scheme in years, and even if I changed it seasonally and needed to log out and back in again, I hardly consider that interrupting my workflow.

I use a light mode during the day, and then at night, I want to be able to use my computer w/o being blinded (ie no white backgrounds) .

Plasma Style can be tied to the color scheme, so changing the color scheme automatically changes the Plasma Style (ie: Breeze Light → Breeze Dark). As a result, I change the color scheme ~2x a day.

Curious if you have an alternative solution that you’re using, or if you are going to lecture me about how using a white background at night builds character…

I wasn’t lecturing you. I just asked a question.

Sorry if I was a little snippy. I think your use case re: color scheme is vastly different from those who care about using dark mode at night, and so your comment was well-intended but potentially not as relevant as it could’ve been.

  1. Can you confirm that you’re using a Plasma style that says in System Settings > Appearance > Plasma Style that it follows the system color scheme?
  2. What is the method by which you change the color scheme?
