How do I enable Audi A8's signature ambient lighting feature?

I recently purchased an Audi A8 and noticed that the interior has ambient lighting that illuminates the interior in different colors. How do I turn this feature on and customize the colors?

To enable Audi A8's ambient lighting feature, press the 'Car' button on the center console and navigate to the 'Settings' option. From there, you can select 'Ambient Lighting' and choose from a variety of colors to customize your interior lighting experience.
