How do I customize the ambient lighting in my BMW 6 Series?

I want to change the color and brightness of the ambient lighting in my BMW 6 Series. Can I do this through the iDrive system or do I need to use a separate app? And what is the best way to sync the lighting with the rest of my interior?

You can change the ambient lighting settings through the iDrive system. Press the 'Settings' button, then select 'Lighting' and finally 'Ambient lighting'. You can choose from a variety of colors and adjust the brightness using the slider.
