GNOME Bugzilla – Bug 782705
display: add setting for Night Light temperature
Last modified: 2018-08-02 10:25:11 UTC
I understand this is a very subjective matter. After using night light for a few weeks, I feel like it should be toned down a notch. When using night shift of the iphone, the warm color toning is subtle and it's not immediately obvious. Looking at my desktop displays it immediately felt off. I think the warm toning needs to be toned down a little.
See https://bugzilla.gnome.org/show_bug.cgi?id=781473 for a more general issue.
I agree with your subjective assessment - on my display it's far redder than even the 2700k lighting I have (which is the warmest commonly available white temperature in a lot of places). It would be great to be able to approximately match the ambient light white point, and since this will be different depending on different people's post-sunset lighting, I think adjustability is the way to go.

There's a dconf key where you can adjust the color temperature: /org/gnome/settings-daemon/plugins/color/night-light-temperature FWIW the default 4000K works well for me. Then again I'm sensitive to light and stay in a darkened room with screen brightness usually between 20%-50% and night light turned on all day with a manual schedule. Not the most representative case, so I'll understand if they change the default, but I hope they keep the option to adjust the temperature.
Reassigning to gnome-control-center to add a UI so that users can change the night time color temperature.
It's worth noting that this isn't entirely about subjectivity - the same supposed colour temperature (i.e. same configured value) looks wildly different on one of my machines vs. the others (extremely orange), so there is a need for user adjustment even to give the same experience as the dev was getting when they chose a specific value.
