[https://github.com/jonls/redshift Redshift] is an open-source software application designed to adjust color temperature of screens based on the time of day.  


Redshift modifies the color temperature to reduce eye strain and improve sleep patterns. The application aims to provide a more comfortable viewing experience by dynamically changing the display's color temperature to match the user's surrounding light conditions.
It does this by gradually shifting the color temperature of the display to reduce the amount of blue light towards the night, and increasing the amount of blue light in the morning.


It does this by gradually shifting the color temperature of the display from cooler (bluer) tones during the day to warmer (redder) tones at night.
Users may choose to have screen temperature automatically match their lighting based my geographic location, or based on manually set time-frames. Users may also customize day and night color temperatures, adjust the speed of transitions, and more.


Users have the flexibility to customize various settings in Redshift. They can specify custom values for day and night color temperatures, adjust the speed of color transitions, and temporarily disable or manually adjust the color temperature.
Redshift is unmaintained and does not support Wayland. It is best used on X11 systems.  


 
For Wayland support you may consider [[Gammastep]], a modern fork of Redshift. Alternatively there is also [[wlsunset]], which is a lightweight modern alternative.
Redshift is currently unmaintained, however [[Gammastep]] is a modern fork of Redshift that supports Wayland. There is also wlsunset which is a lightweight modern alternative.
