Calendar colors: Don't overwrite when not set by server

[rfc2822]

Scope

• [X] I'm sure that this feature request belongs here and not into Discussions.

Description

1. When a server does not send a calendar color we don't need to overwrite it with our "green" every time (only use green when calendar is created). Users can then change the calendar color with a third party app and DAVx5 won't overwrite the changes.
2. Maybe we shouldn't use green for all unknown calendars but select random? different colors. People don't see only green calendars then without possibility to distinguish between them.

Further info

Can we just not update the calendar color in LocalCalendar.update() when it's null from the server? (But of course set it in LocalCalendar.create, otherwise the calendar will be transparent)

Or if it's not fully out of scope of the app, please integrate a color picker to set the calendar colors manually. I just disabled the calendar color sync in DAVx and noticed that even then the tasks.org app doesn't let me change the colors. The same with jtx. And the "Calendar Color" App mentioned on https://www.davx5.com/faq/change-calendar-color/ is very old and doesn't support tasks-lists without calendar.

Has anybody a workaround for my usecase? My caldav provider (vikunja) doesn't seem to support synced calendar colors atm.

Isn't that a bug? I don't want to force you to anything, and I'm thankful for developing, but after a while it's a bit annoying that the color changes always to complete different one, which I don't expect.

[rfc2822]

~~Which one would you expect, when the server doesn't send one? Did you disable the "manage calendar colors" setting in the Account settings? Did you set them with a calendar app or a seperate app? Which one?~~

I think we have all necessary information
