A screen fixed to one white balance can look too blue under warm indoor lighting. True Tone on iPhone and iPad uses the device's sensors to adjust the display's color and intensity to match the ambient light, so images look more natural as the surroundings change.
True Tone is on by default and needs no adjustment, so the only choice is whether to keep it running. With it off, the display holds the same color and intensity regardless of the light around it, which suits work where colors must stay fixed, such as editing photos.
Some accessibility settings, including Invert Colors, Grayscale and Increase Contrast, might turn True Tone off, and Reference Mode on iPad disables it. Check those settings first if True Tone stops working after being enabled.
True Tone adjusts automatically to match the ambient light, helping reduce eye strain.
Steps to adjust display color using True Tone:
- Open Settings.
- Scroll down and tap Display & Brightness.
- Toggle True Tone to enable or disable it.
