The screen of my laptop (Dell XPS 15) is rather blue. I found that I can tweak it a little bit with redshift. During the day, 6000K is the perfect temperature, in the evening I tend to use 5500K.
Ubuntu has the Night Light option, so I was wondering if I just can reconfigure the day and night colors to be the ones I now manually set with redshift. Because redshift does not persist the settings. Even after just closing my laptop, those settings are gone.
So how can I configure Night Light for both day and evening temperatures?
As described here, it's possible to configure the NIGHT color using the following command:
gsettings set org.gnome.settings-daemon.plugins.color night-light-temperature <temperature>
But is it also possible to configure the DAY color as well?
