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 (please see this post for the reason why I started this project).

Download

Latest release is Redshift 1.8 published on 2013-10-21. Packages are available from most distributions. In addition the following downloads are available:

Source code: Available from Github

Windows: Experimental builds (it’s a command line utility; be aware of windows limitations):

Redshift 1.7 (x86)

Redshift 1.4 (x86, x86_64)

Project page

I am currently moving development to Github. Issues and pull requests can be posted there. The old bug tracker is still present at the launchpad project page, but I will gradually be moving over to Github for that as well.

Project description

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.

Technical details

On linux and similar systems the color temperature is set with an X server extension. On the windows platform it is set using GDI. The color temperature is changed 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.

Light change before sleep

Combine this with using Calibre to move your reading to an eInk-based eReader 30 to 90 minutes before bed. You can establish and maintain a good sleep cycle while sacrificing as little modern convenience as possible.
