Describe the issue you are experiencing
Automation Category Picker Selected Row Ignores Dark Theme (White on White)
Home Assistant Version: 2025.x (latest)
Frontend Mode: Default (no custom CSS, no frontend hacks)
Theme Type: Standard YAML theme (OLED / true black)
Install Type: Home Assistant OS / Supervised
Theme Loading: frontend:
themes: !include_dir_merge_named themes
In Settings → Automations → Edit → Category Picker, the selected category row is permanently white, regardless of theme settings.
This results in:
White background on the selected row
White / nearly-white text on top
Selected item becomes difficult or impossible to read in dark themes
This issue persists even when all documented theme variables are defined, including:
paper-item-selected-background-color
paper-item-selected-text-color
mdc-theme-*
mdc-sys-color-*
All other parts of the UI respect the theme correctly.
Describe the behavior you expected
The selected row in the category picker should:
Respect the active theme background color
Respect the active theme text color
Behave consistently with other dropdown and list components
