    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

    • Free & open source
    • Adds the feature of setting your own sunset and sunrise times, which the f.lux developer(s) did not want to add
    • Access to the keyboard/mouse logging hook MSCTF.dll can be declined without affecting functionality except for the ability to configure quick-keys
    • Occasionally crashes when denied a permission by comodo HIPS, but nothing so regular that it gets in the way of use.

    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.

    Dimmer vs f.lux opinions
    This alternative is disputed. Dimmer is still a legitimate alternative to f.lux, but it might have issues that some users think are important.

    Dimmer controls monitor's brightness not color temperature.
