Gammastep is a utility that adjusts the color temperature of your display according to the time of day, your location, or a manually defined schedule.
It’s intended to make the screen warmer at night and cooler during the day, which can help reduce eye strain when you’re working in front of a monitor for long periods. The software offers flexible configuration through command-line options and an optional configuration file, making it suitable for both simple setups and more customised desktop environments.
This is free and open source software.
