What is Color Temperature (Change Lux)?

Color Temperature (Change Lux) is a Firefox add-on that acts as a sunglass for your computer screen. It adjusts the color temperature of the screen, adding a warm hue which is easier on eyes especially during night or in a dark environment. The functions are easily accessible via a toolbar panel UI and include an ON|OFF switch for quick enable/disable. You can whitelist certain sites to exclude them from color change, which can be facilitated using addon shortcuts. Adjust your settings via the options page, for a comfortable browsing experience, reduced blue light exposure and better sleep.
