How can I get color from CalendarEvent object on google apps script?

I want to get the color(red) below the picture.

enter image description here

I use next code, but I don’t know next step.

run main function.

var mainCalendarName = 'main';
function main() {
    var calendar = getCalendar();
    if (calendar == null) {
    var now = new Date();
    var calendarEventArray = calendar.getEventsForDay(now);
    Logger.log('current color = ' + calendarEventArray[0].getColor()); // not use!!!
    //log 'current color = #FF0000'
function getCalendar() {
    var calendarList = CalendarApp.getAllCalendars();
    for (i in calendarList) {
        if (mainCalendarName === calendarList[i].getName()) {
            return calendarList[i];
    return null;


First of all you need to enable the Advanced Google Services.

Please see here description how do that.

Then the following code will do the job

function main(){
  var now = new Date();
  var events = Calendar.Events.list("main", {
    timeMin: now.toISOString(),
    singleEvents: true,
    orderBy: 'startTime',
    maxResults: 10
    for (var i = 0; i < events.items.length; i++) {
       Logger.log(events.items[i].colorId); //Here the color of the specific event
