Light Mode is the standard macOS color scheme. It uses black text on a white background. You may prefer to use this in bright workspaces or during the daytime. Dark Mode inverts the standard colors, with light text on a black background. This highlights the information you’re using while toning down background windows and buttons. You may prefer to use this in darker rooms or after sunset. Auto Mode turns on Light Mode during the day and Dark Mode in the evening based on local sunrise and sunset times. Light Mode and Dark Mode activate immediately when selected so you can easily switch between them from the same screen to see the difference.
If Auto Mode is enabled, your computer will maintain its schedule and the display will change back to Light Mode at sunrise. Control Center is an easy way to switch between color schemes temporarily.
