Redshift adjusts the color temperature of your screen according to your surroundings. This may help your eyes hurt less if you are working in front of the screen at night. This program is inspired by f.lux. Redshift adjusts the color temperature according to the position of the sun. A different color temperature is set during night and daytime. During twilight and early morning, the color temperature transitions smoothly from night to daytime temperature to allow your eyes to slowly adapt. At night the color temperature should be set to match the lamps in your room. This is typically a low temperature at around 3000K-4000K (default is 3700K). During the day, the color temperature should match the light from outside, typically around 5500K-6500K (default is 5500K). The light has a higher temperature on an overcast day.
Features
- On linux and similar systems the color temperature is set with an X server extension
- n the windows platform it is set using GDI
- The color temperature is changed by setting appropriate gamma ramps
- Your graphics driver and X server needs to either support at least RANDR version 1.3 or the VidMode extension
- Redshift can also be applied to the Linux console by explicitly selecting the DRM driver
- Redshift will continously update the color temperature at regular intervals
