User receives prompt on login: "Authentication is required to create a color managed device"

[Daniel Richard G.]

This concerns colord 1.4.4-2 in Ubuntu focal. (xiccd 0.3.0-1 may also be relevant.)

I log into the Xfce desktop environment, and immediately see an "Authenticate" window pop up:

    Authentication is required to create a color managed device

    Password for root: ________

    Action: org.freedesktop.color-manager.create-device
    Vendor: System Color Manager

I see this in syslog:

    Apr 8 05:38:30 test-ubuntu64 dbus-daemon[573]: [system] Activating via systemd: service name='org.freedesktop.ColorManager' unit='colord.service' requested by ':1.35' (uid=1000 pid=1475 comm="xiccd " label="unconfined")

This prompt is confusing to ordinary users, and I do not understand why it should even be necessary.

Note: My use case involves logging into the desktop remotely, via XRDP. This issue appears to affect other remote-login implementations as well.
