eventColor

Sets the color for all events on the calendar. The theme uses this value to determine how the event looks (background, border, etc).

You can change the color of all events on the calendar like so:

var calendar = new Calendar(calendarEl, {
  events: [
    // my event data
  ],
  eventColor: '#378006'
});

You can use any of the CSS color formats such #f00, #ff0000, rgb(255,0,0), or red.

The eventContrastColor option can be used to set the contrast color for text and other elements rendered on top of the event.

This option can be overridden on a per-source basis with the color Event Source Object option or on a per-event basis with the color Event Object option.
