Add colour temperature setting to night light dialog
There are requests to modify the nighttime (and daytime) color temperatures. There is no support to modify the daytime color temperature, and my expectation is that this is not desirable to add this feature to gnome-settings-daemon.
See for example: https://bugzilla.gnome.org/show_bug.cgi?id=781473
I don't expect that this will be added to the control-center night light configuration, so if anywhere, it could be added to Tweak tools.
Feel free to move back to control-center if it is decided to be the better place.
