Colour correction is an experimental feature and might not work correctly everywhere on your phone.

To replace all screen colours with grey tones, choose Greyscale. Or, correct colours based on your vision:
| How you see colours | Option to choose |
|---|---|
| It's difficult to tell violet from blue. Yellow and green appear redder. | Red-green (Green weak, deuteranomaly) |
| Colours aren't bright. Red, orange and yellow appear greener. | Red-green (Red weak, protanomaly) |
| It's difficult to tell yellow and red from pink. Blue appears greener. | Blue-yellow (Tritanomaly) |
If colours don't appear as you expect, troubleshoot the issue.

If you're using Dark theme to reduce eye strain when reading, you might encounter specific apps that don’t support it and still have a light background. Turn Colour inversion on to use those apps with a dark background. You can use quick settings or a shortcut to easily turn Colour inversion on and off.
