  • Color profiles?

    Color profiles?

    In the evening I like to have a blue filter for my screen.
    Tried several suggestions but nothing works.
    However I do have "Color profiles" in my menu and selecting
    "D50" does reduce the brightness and blue quite a bit.

    Is there something better which can be used a blue night filter?

    applets/QRedshift or Redshift. This might not work in your setup but I
    didn't have a problem.
    preferences/NightLight.

    (TL; DR - jump to bottom, Night Light)

    Since I had no idea of what you are talking about, I traveled this path:

    Menu/ Color/ (Each device needs a color profile to be managed)/ My
    monitor's model/

    Color Management Integration For The Gnome Desktop Environment -
    GNOME Color Manager is a set of graphical utilities for color
    management to be used in the GNOME desktop. With the help of
    ArgyllCMS, it can create and apply display ICC color profiles.

    Install/y/n

    Synaptic:
    With the help of ArgyllCMS, it can create and apply display ICC
    color profiles.

    Visit homepage: https://git.gnome.org/browse/gnome-color-manager

    To adjust your monitor for nighttime use, consider enabling the
    "Night Light" feature in Windows, which reduces blue light emission.

    Linux:
    To reduce blue light emission on Linux, you can utilize software
    like Redshift or Night Light (available in newer GNOME versions).
    Redshift is an open-source tool that adjusts the color temperature
    of your screen, reducing blue light based on time of day. Night
    Light, found in GNOME's display settings, offers a similar
    function.

    After learning that, I found Night Light in my menu

    You donrCOt want blue before bed, you want the opposite of blue. Blue will make it harder to go to sleep.

    a blue filter filters out blue light. my monitor has a blue light filter
    built in, and I can even vary the intensity of it
