Hi,

I would like to use the

The Night Light filter, also known as Blue Light filter or Color 
Temperature filter,

Is there a package in Guix to support this?

I am using MATE Desktop and I couldn’t find anything.

I heard that Gnome supports that, also KDE but both I haven’t installed 
(yet).
I don’t know if Enlightenment Desktop has that option, but because of 
several problems I don’t use Enlightenment often.

My laptop Tuxedo (german company) supports that, but to enable it in 
Guix, I would have to write a programme to use the Tuxedo programme, 
which is impossible for me.

Kind regards
