True Tone technology makes images on your Retina display and Touch Bar appear more natural. In Mac computers, True Tone uses advanced multichannel sensors to adjust the color and intensity of your display and Touch Bar to match ambient light, enhancing the natural appearance of images.
Using True Tone on Mac Choose Apple menu > System Preferences, then click Displays in the sidebar.
Select your display at the top of the window. Turn on True Tone in the settings that appear for the selected display.
This setting is only available for displays with original Apple parts.
