Color Temperature (Change Lux) is a lightweight tool that lets you change the color of your screen to make it more pleasant. This app can be used to make your screen more colorful. It is compatible with the latest versions of Chrome and Firefox. 

To start using it, simply press the button on the right and then choose the color you want. You can choose from several options, such as green, orange, pink, blue, and purple. You can also set it to warm. It is also compatible with the night mode. If you don't know how to set it, just press the button that says "Warm" or "Day" and it will be automatically set.

The way it works is that it takes into account the color of the ambient and the color of your screen. It then uses a formula to determine the correct color to match the environment.
