This question you are referring to does not match. He was looking to change the background color of any day in which there is an event, and not the event itself. What you are trying to do is supported by the library. You can set the color of the event by passing the event data in the color property.
All examples can be found on the FullCalendar Event Source Object page. As indicated on this example page, you can set it in an array of events:
{ events: [ { title: 'Event1', start: '2011-04-04' }, { title: 'Event2', start: '2011-05-05' }
or in JSON:
{ url: '/myfeed.php', color: 'yellow', // an option! textColor: 'black' // an option! }
Now they set the background for each event in the source, but you can do this for each event, just like:
[ { "title": "Free Pizza", "allday": "false", "borderColor": "#5173DA", "color": "#99ABEA", "textColor": "#000000", "description": "Fake description for the Free Pizza", "start": "2014-11-15T16:30:28", "end": "2014-11-15T17:30:28", "url": "some url" }, { "title": "CSS Meetup", "allday": "false", "borderColor": "#820F20", "color": "#A6113C", "textColor": "#ffffff", "description": "Fake description", "start": "2014-11-19T16:30:28", "end": "2014-11-19T18:30:28", "url": "someUrl } ]
You can use eventColor and eventTextColor ( src ) to set the background for all events in the calendar, e.g.
$('#fullCal').fullCalendar({ events: [...], eventColor: 'yellow', eventTextColor: 'black' });
After further refinement, it looks like you want certain time intervals to have colors, but not to be a βrealβ event. You can do this in FullCalendar 2.2 with Background Events by adding rendering: 'background' to the event ( documentation ).
$('#fullCal').fullCalendar({ events: [{ title: 'Main Event 1', start: moment().add(-4, 'h'), end: moment().add(-2, 'h'), color: '#ff0000', allDay: false }, { start: moment().add(2, 'h'), end: moment().add(5, 'h'), rendering: 'background' }, { title: 'Main Event 2', start: moment().add(5, 'h'), end: moment().add(7, 'h'), color: '#00cc00', allDay: false, fakeEvent: false }], header: { left: '', center: 'prev title next', right: '' }, timezone: 'local', defaultView: 'agendaWeek' });
