How do I get the Redshift functionality of smart adjustment of the color temperature throughout the day in a Wayland session of Ubuntu 17.10?

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.

  1. 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?

  2. 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.
