        Hi,
you left some questions unanswered, thus this thread is partly about
"guess and (maybe) hit", which is not good, because it only adds to the
confusion. See Patrick's first email in this thread with his questions,
all are important. That's the reason why he asks them.

As had been said, "less secure" is just a term of the Google server for
the clients which do not use OAuth2. If you want to use it, then
configure a Google account in the GNOME Online Accounts (GOA),
accessible through gnome-control-center. You only not get "more secure"
application, but also all the calendars, address books, a task list and
more (if you enable that part in GOA), as you've configured on the
server, by one hit, named as they are on the Google server, calendars
with assigned color as you have on the Google server [1] and so on.
(Well, some parts of this depend on your exact version of the Evolution
and the Evolution-Data-Server).

With Evolution 3.20.x+, a newly created Google calendar inside the
Evolution will also use OAuth2, but it will not assign "the server-side 
color" on its own, unless you pick the calendar from a list of
available calendars. Your version (I hope it's not any ancient) have it
too, just right-click the Google calendar and pick "Properties", then
click the "Find Calendars" button, which is the time when the Evolution
asks for the available calendars and their properties and shows them to
the user. It shows the correct name, correct color and even the
description of the calendar, if it's available (the Google server
provides all three parts). When you pick the calendar from the loaded
list, the calendar properties will change to match those server-side.

        Bye,
        Milan

[1] It's an Apple extension, but supported by most of the CalDAV
servers; all I use for testing. It's a "calendar-color" property in an
"http://apple.com/ns/ical/" namespace.
