This is very tiny Chrome/Opera extension I’ve made for myself. Its kind of night mode extension which purpose is to make webpage area more accessible in dark environment e.g. at night by turning bright backgrounds down. It attempts to dim background of every single website element and change color of a text and other elements into more readable one. There are couple of customization options but not too many to preserve simplicity (this may change in the future, who knows…). The goal is to make it work with any website not just a couple of predefined ones. Having said that I’m aware of the fact that it doesn’t work perfectly with every single existing website but for those I usually visit – works quite well :).
If you like to check it you can get it from the Chrome Webstore or Opera add-ons websites.
