This extension inverts all images on a website. This is meant to be used together with screen inverting that comes with OS X
Using the OS X built in screen inverting is very convenient for low-light settings, e.g. at night, with all lights off. But there's one problem: browsing Websites is awful because all the images are inverted. This Google Chrome plugin aims to solve this problem.
To use this plugin with OS X screen inverting, follow these steps:
1) Invert Colors for whole screen
System Preferences > Accessibility > Display
activate "invert colors"
2) Invert images on website with this plugin
Go to any website and klick the plugin's icon the invert the inverted images, effectively making them normal again.
Create a global keyboard shortcut to invert your screen. See:
