Hi!
If you’re using redshift on Linux, I made a small tool that might be useful. It automatically sets the screen temperature based on the current time, you just draw a curve for how you want it to behave during the day. Then you can just add it to crontab to run every minute or hour.
Can you adjust separate curves for red, green and blue?
Nope, currently just temperature. But it can definitely be added, since redshift supports it.
That would be a powerful feature and a very user-friendly way of creating what are essentially custom monitor profiles. It has my vote!
