Redshift - Jon Lund Steffensen Description

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 uses an X server extension to adjust the color temperature. This is done by setting appropriate gamma ramps. If you have configured your own gamma ramps they will be overwritten but in that case you probably care too much about color accuracy to use this program anyway. Your graphics driver and X server needs to either support at least RANDR version 1.3 or the VidMode extension. The color temperature is set 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. Redshift will continously update the color temperature at regular intervals. One shot mode can be selected if you only want to do one adjustment. The color adjustments done by Redshift can be temporarily toggled on and off by sending it the USR1 signal.
