1. pick windows style in qt6ct
2. select darker as the colorscheme
3. apply

Expected behavior

the selected color palette should be applied

Screenshots

Additional context

• on qbitorrent qt6 the custom palette works
• i have tried setting the kde colorscheme in ~/.config/kdeglobals but that does not work for dolphin
  • on kdeconnect settings the kdeglobals solution works
• might be relevant: [Bug]: dolphin background won't follow the theme prasanthrangan/hyprdots#1843

It seems to be working fine for me. Is it possible that some random configuration is causing this?

[Gliczy]

It's working fine for me as well. Could you share the relevant config?
Also, to be sure, could you check that you are using pkgs.kdePackages.dolphin and not pkgs.libsForQt5.dolphin?

[zspher]

yup, im using kdePackages.dolphin

ive used plasma6 setting to set dolphin themes but that still does not work
the color theme only uses the default breeze theme
also when i set via qt6ct the theme is applied and the removed on new dolphin startup
