CalDAV clients like DAVx⁵ use the ICAL:calendar-color property to determine the calendar’s color. However, this property is missing, so DAVx⁵ simply defaults to green, which makes things very difficult to differentiate. There is already a feature request to be able to change the color manually: Allow to override title of collections locally · Issue #1002 · bitfireAT/davx5-ose · GitHub .
Since it’s currently unknown when this feature will be implemented, I wanted to ask if it could be implemented in Stalwart.
Another advantage would be that the color would then automatically be the same across multiple devices, reducing the need to manually adjust it on each one.
The XML structure for this can be viewed, for example, in the Radicale repository: Radicale/SHARING.md at master · Kozea/Radicale · GitHub
