Scenario:

I accidently inverted my colors on my iOS device, how do I reset them to normal?

Solution:

This can sometimes happen, especially on slow devices when you triple click the home button (on a device that’s running slow or is unresponsive iOS may see multiple presses of the home button as a triple click). By default, the triple click is setup to toggle the inverting of colors (You can change this behavior also and disable that default). To quickly un-invert the colors you can use one of these two methods:

1. Triple click the home button again. Sometimes on devices that are running slow this option is inconsistent.
2. Go into Settings->Accessibility and toggle the “Invert Colors” slider to off.
