Ubuntu – How to change the color of the marker on the dash that indicates an application is “up”

accessibilitygnome-shellubuntu-dock

Is is possible to change the dot on the Dash (or Dock) icon to yellow or green so I can see it?

I am very colour blind. In particular, I simply can barely detect red light. There is a small dot (I finally realised) on the Dash that indicates that an application has a window open or that the application is running. I just need to be able to see it without spending ten or fifteen seconds trying different angles and staring to determine whether an application is already running.

Ubuntu 18.04; up-to-date.

  • in normal GNOME environment

    gsettings get org.gnome.shell.extensions.dash-to-dock custom-theme-running-dots-color
    

    will give the present color

    Example:

    maduri@i7-4770U:~$ gsettings get org.gnome.shell.extensions.dash-to-dock custom-theme-running-dots-color
    '#0000FF'
    maduri@i7-4770U:~
    

    to set the required color..

    gsettings set org.gnome.shell.extensions.dash-to-dock custom-theme-running-dots-color "#0000FF"
    

    for yellow or green color your can replace "#0000FF" with "yellow" or "green".

    Alternatively you can use the GUI tool dconf-editor like below

    changing the color of "running-dot"

    Note: dconf-editor isn't present by default. You can install it from the Software Center.


    You can also make the dot bigger:

    For example, to do so run

    gsettings list-recursively | grep running-dot
    

    You'll get output like this:

    dkb@dkb:~$ gsettings list-recursively | grep running-dot
    ca.desrt.dconf-editor.Settings saved-view '/org/gnome/shell/extensions/dash-to-dock/custom-theme-running-dots-border-width'
    org.gnome.shell.extensions.dash-to-dock custom-theme-customize-running-dots true
    org.gnome.shell.extensions.dash-to-dock custom-theme-running-dots-border-color '#e95420'
    org.gnome.shell.extensions.dash-to-dock custom-theme-running-dots-border-width 2
    org.gnome.shell.extensions.dash-to-dock custom-theme-running-dots-color '#e95420'
    dkb@dkb:~$ 
    

    Then, open dconf-editor as in the image below and make the desired change:
