what is true tone iphone

True Tone is a feature available on iPhones that uses advanced sensors to adjust the color and intensity of the display to match the ambient light, so that images appear more natural. It automatically balances the color temperature of the display with the surrounding environment, making it easier on the eyes. If you turn off True Tone, the display keeps color and intensity constant, regardless of changes in the ambient light. Some display accessibility settings, including Invert Colors, Grayscale, and Increase Contrast, might turn off True Tone. True Tone can be turned on or off in the Display & Brightness settings.
