Redshift is a neat little program allowing you to adjust color temperature of the screen during the day and separately during the night. Is it possible to achieve this with GNOME 3 on Ubuntu 17.10?

Under Setting → Devices → Displays GNOME allows to enable Night Light which makes the screen somewhat warmer at night. However, it does not allow to adjust the color temperature, and it doesn't work during the day.

How to replicate the Redshift functionality in Gnome 3 on Wayland?

    If you do not need Wayland for real, you can login to the Ubuntu on Xorg session and try redshift here. – N0rbert Oct 22 '17 at 18:18

    @N0rbert Thanks. I decided to go even a step further and run Unity for a while longer. From the same menu. Redshift still works there. – Damn Terminal Oct 22 '17 at 18:44

    See https://bugs.launchpad.net/redshift/+bug/1431645 . The wayland solution is nightlight - https://www.gnome.org/news/2017/03/gnome-3-24-released/attachment/night-light/ – Panther Oct 22 '17 at 18:54

Not really a good one but kinda half-baked solution is using a GNOME shell extension called "Night Light Slider". It adds a slider to control the colour temperature manually:

Also you may change Night Light's colour temperature using dconf Editor/gsettings as suggested here: How to adjust the hue (intencity) of gnome night light?

    @Panther it's an extension for night light, it just adds a temperature slider for night light in the system menu. OP is aware of night light, they just want a more intelligent temperature shift option like redshift offers. – pomsky Oct 22 '17 at 18:57

TLDR;

Just for the quick reader who didn't read the whole OP question:

Here is a screenshot of the Solution Ubuntu offers since 17.10, the built-in feature like redshift called "Night Light":

The Night Light feature is extremely easy to enable. We just need to open Settings, and then go to Devices → Display. Here we need to move the button next to Night Light to the “on” position.
