hyprsunset [options]

hyprsunset is a blue light filter for Hyprland, the dynamic tiling Wayland compositor. It adjusts screen color temperature to reduce blue light emission, which can help reduce eye strain and improve sleep quality during evening computer use.
The service can be configured via ~/.config/hypr/hyprsunset.conf or command-line options. Once running, settings can be adjusted dynamically using hyprctl commands without restarting the service.
Lower temperature values (e.g., 3000K-4000K) produce warmer, more orange-tinted colors suitable for night use. The default 6000K represents standard daylight white.

-t, --temperature KELVIN

Set color temperature in Kelvin (lower is warmer)

Set gamma percentage

Only works with Hyprland compositor. Requires Hyprland to be running. Changes affect all monitors. May interfere with color-accurate work like photo editing.

hyprsunset is part of the Hyprland ecosystem, created by Vaxry. It provides functionality similar to redshift or gammastep but specifically designed for the Hyprland Wayland compositor.
