Your iPhone, iPad or Mac allows you to control the color temperature of your display for a more natural and comfortable experience.

True Tone adjusts the color of your display based on the ambient light detected by its sensors (where those sensors are present in the display or device). With True Tone, the white background on your display will appear more like paper in your current environment. This can give you a more natural reading experience.

Night Shift adjusts the color of your display based on the setting and rising of the sun or according to the schedule you specify.

Some studies have shown that too much "blue light" from a digital display right before sleep can worsen our ability to sleep well. Night Shift lessens the amount of blue light which may help you sleep better.
