The feature to display reverse colors is an experimental one. It might affect the performance of games and apps. So use it with caution. This experimental feature inverts your whites to blacks, red to green, blue to yellow, and so on. Inverting this way and using a darker scheme will allow your device’s screen to eat up less of the battery juice. It also increases accessibility and visibility for certain people.
So, to enable inverted colors for your screen in Android Marshmallow devices:
- Go to the main Settings.
- Scroll down to System > Accessibility and tap on it.
- Scroll down to Display and you will find an option called Color inversion.
- Tap and move the slider towards the right.
Not everyone will prefer or want to keep this feature on. You can move the same slider towards the left to turn off color inversion. It will instantly switch back to the default color scheme and everything will appear natural.
