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 eventBackgroundColor, eventBorderColor, and eventTextColor options can be used for more granularity.

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.
