You can define a calendar color. By default, all appointments in this calendar will be displayed in the color of the calendar. If you assign an individual color to an appointment when creating or editing it, the appointment will be displayed in the color assigned, not in the color of the calendar.
How to select a calendar color:
Select a calendar in the folder view. Click theicon next to the calendar.
Select a color from the color selection drop down.
