From the Home Assistant Core 2022.12 release, we are using different colors per domain when an entity is active. These CSS variables are no longer used:
This means that any theme that has previously overridden these CSS variables will use the built-in colors for active states. All theses new colors are available as CSS variables too.
As we only officially support the
accent-color properties for themes, some colors can be added or removed between releases.
More details about theme configuration can be found in the Home Assistant documentation.
