Like the built-in implementations by Windows 10 and Gnome, the new Night Color feature of KDE missed an essential feature of redshift and similar third-party programs: allowing users to set the (top) day color value. This allows people to completely limit the range to be used throughout the entire day.
Comment 1 Roman Gilg 2018-02-07 22:53:26 UTC 
The idea was to put the daytime/overall color temperature value in the end in a separate KCM, that replaces KGamma on Wayland and handles all color correction. This should then also do this per screen.

The nighttime color temperature value would then be a relative delta to the daytime/overall color temperature value on each screen.

Fine with that?
Comment 2 KDE Neon user 2018-02-08 16:49:31 UTC 
That makes sense, since you control the system settings directly.

Could the Night Color KCM somehow link to the main color KCM you've mentioned, so users who are used to setting it through third-party Night Color-like programs can easily find it?

I look at the code of night color so it will be better to be distinct kcm, also note that's good feature, by myself i'm using it for years (at days as well) so that's missing in Wayland.
Comment 4 Anthony Fieroni 2019-10-27 15:29:02 UTC 
I'm fine with 'Constant mode' it makes sense to me since i use ~4000k temp.
Comment 5 Pierpaolo Valerio 2020-11-08 09:12:09 UTC 
Any news on this issue? Personally this single-handedly makes wayland unusable for me, as I wouldn't be able to run redshift to adjust my screen temperature.

I'd also like/need an option to set the day-time monitor colour temperature. This is one of the features I have been missing the most and already wanted to ask for since a longer time.
Currently I open the night colours kcm many times a day and set the temperature manually, but that's tedious.
My dream would be the possibility to make a custom graph for the colour temperature over the day, but that's probably a bit too fulsome...
A simple day-time setting would really be enough and a great improvement that I'd love to see on the next Nate Graham "This week in kde" blog post 😊🙈
