About:
Redshift adjusts the color temperature of your screen to match the time of day, reducing blue light exposure during evening hours. This helps minimize eye strain and can improve sleep quality by aligning your screen's light spectrum with natural circadian rhythms. The tool is highly configurable and supports automatic location detection for precise sunrise and sunset adjustments.

Key Features:

Automatic location detection via GPS or geoclue
Manual temperature and brightness control
Low resource usage and system tray integration
Cross-platform support including X11 and Wayland

Use Cases:

Reducing eye fatigue during late-night coding or reading sessions
Automatically adjusting screen temperature based on geographic location

Alternatives:

f.lux – Proprietary alternative with similar functionality but closed source
sct – Simpler tool that sets color temperature once without automatic scheduling
