True Tone is a new technology on iPhone X screens that use multiple sensors. This feature can help you get a more natural white color while outdoors, in a dark room with more yellow light or some other activities. Rather than use any special display hardware, True Tone subtly adjusts the white balance onscreen to match the color temperature of light around you whether you’re using the device under overhead lighting or in direct sunlight. The goal is to fool your eye into perceiving the screen looks white like paper in any light.

When to Use True Tone?
Apple gives True Tone to make iOS users who often look at the screen for a long time to be more comfortable. Especially for those of you who are often in some rooms that have different lights either darker, brighter, bluish or yellow color lights. All these conditions can be neutralized by True Tone and make you see the white on the screen becomes more natural.
