These are instructions on how to enable or disable True Tone in macOS.
True Tone uses multichannel sensors to adjust the color and intensity of your display to match ambient lighting conditions. This results in cooler whites during the day and warmer whites at night.
Step One Select System Preferences from the Apple menu at the top left of your screen.
Step Two Choose Display from the System Preferences menu.
Step Three Toggle the True Tone checkbox to turn the feature ON or OFF.
