Is there an easy way to invert colors? iOS has a nice option in the accessibility menu that allows you to invert the screen colors. Does Android have anything like this?
Since Android 5.0 Lollipop, the feature is built-in as one of accessibility options.


Open Settings
Select Accessibility
Below Display section, toggle Color inversion.


After toggling it for the first time, the "Invert colors" toggle will be added to the quick settings menu.
