Line 3:

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.

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.

Redshift is best used on X11 systems as it is unmaintained and does not support Wayland.

You can find more options in [https://nix-community.github.io/home-manager/options.xhtml#opt-services.redshift.enable Home Manager: services.redshift]. This configuration defines the temperature the display will use at night and day, the schedule and length of the transition, brightness for the display to use, and whether it will use a tray icon. <code>extraOptions</code> defines additional command-line arguments to pass to <code>redshift</code>.

===== Location Based Transitions =====

You can choose to use Redshift with location based screen temperature to match when the sun actually sets and rises in your area. Below are examples of those options using [https://gitlab.freedesktop.org/geoclue/geoclue/-/wikis/home Geoclue] and manually set coordinates.
