    It adjusts colours the way I expected it to. There is a simple and efficient gui applet (redshift-gtk) available, and it supports interesting commandline options

    So happy I can set my own times. In the winter the sunsets happened way to earlier in Flux, then I'd turn it off and forget to turn it back on.
