Google is rolling out Android Auto version 13.4, which incorporates its Material You design language, enhancing the visual experience with vibrant accent colors that align with users' phone settings. This update applies new accent colors to various system elements such as buttons, toggles, and backgrounds of cards and menus, extending functionality beyond music applications. Users can see these changes in the Settings menu, notifications, and notification center, but the feature does not yet apply to third-party apps. To experience the new color scheme, users must enable the setting that matches the phone’s wallpaper. There are reports of inconsistencies, with some colors not updating in real-time, necessitating a force stop of the app and reconnection to see the changes.
