How do you get your iPad display to look less yellow or blue and more paper white? With Apple's new True Tone technology!
True Tone was designed to make looking at a screen more like looking at a sheet of paper. By using four-channel ambient light sensors to match the lighting around you, the screen adjusts its color temperature (think warm and cool colors) for a more natural and balanced look. This makes reading and browsing more comfortable.
Note: True Tone is currently only available on the 9.7-inch iPad Pro.
How to turn on True Tone
Launch Settings from your Home screen.
Tap on Display & Brightness.
Switch True Tone to On. The switch should be green.
Note: True Tone is automatically disabled when it could adversely affect color-sensitive tasks like photo editing.
