That&#x27;s a good question.<p>It is worth noting that during the day you should NOT use night mode even in a dark environment, the whole point of the color shifting is to reproduce how the sun interacts with the world around you, turning on night mode during the day won&#x27;t do your internal clock any favours.<p>That being said, there might be good arguments for having manual night mode control, like if you&#x27;re a night shift worker and want day mode at night, and night mode during the day. And a lot of international travel scenarios.
