A lot of people use "night mode" tools to adjust the white balance of their computer screen in hopes of getting better sleep and to avoid screens from blinding you with their bright light. These tools reduce the eerie blue glow of computer screens by shifting the white balance to warmer, redder tints at night.
Due to its popularity, it seems Microsoft is going to implement a night mode feature in a future version of Windows 10. The future popped up in the latest Windows insider build and signs are that it will have a quick access button in the Action Center:
Apple recently built a color shifting feature into iOS, under the name Night Shift, and there are now signs that Microsoft is doing the same in Windows 10. Twitter user tfwboredom has been poking around the latest Windows insider build and found hints that the operating system will soon have a "blue light reduction" mode. Similarly to f.lux, this will automatically reduce the color temperature in the evenings as the sun sets and increase it in the mornings when the sun rises.
Signs are that the feature will have a quick access button in the Action Center when it is eventually enabled.
