Hello @MeagLane ,
Welcome to Q&A Forum!
According to my research and search, We cannot set JSON formatting for Choice column in a Calendar list.
However, you could try to the below workaround:
Adding Colors to Event Categories with Overlay Feature:
1.Create a Choice column naemd "Types" and set it as the required field.
2.Create three Calendar Views
ALL view:
- Make this view the default and public view
- Filter: Title is equal to null(empty)
EROC view:
- Make this view the public view
- Filter: Types is equal to EROC
AROC view:
- Make this view the public view
- Filter: Types is equal to AROC
3.Go to the Calendar list, on the CALENDAR tab, click on Calendars Overlay.
4.On the Calendar Overlay Settings page, click on New Calendar to create two calendars
EROC:
- Please click "Resolve" button, and select the corresponding list and list view
- Select the "Always show" checkbox.
AROC:
- Please click "Resolve" button, and select the corresponding list and list view
- Select the "Always show" checkbox.
5.Go to the Calendar list, you will see as below:
Thanks,
