How can I change general color of calendar(s)?

Dear community,

how is it possible to change the ‘default’ general color of synced calendars?
Searched within Etar, account settings and on the server side without getting a clue.

Thanks for any hint,

You change it on the server side. Normally it’s in three dots menu (edit name, edit color) but somehow its hidden in ecloud.

You can use ‘simple calendar’. There you can pimp what ever you want

Yes, works fine, thanks!

Found the options on another NextCloud… thanks.
When trying it on ecloud (calendar properties), a wrong frame is displayed on the left side. Is this a bug or general config error?
