@sdetweil, that didn’t quite help. If I make coloredBackground true in .js, the events are whited out.

Not all my events have a background color. I am using the below code and MMM-CalendarExt3. Any help would be appreciated.

{
			module: "calendar",
			header: "Calendar",
			position: "top_left",
			config: {
				calendars: [
					{
						fetchInterval: 7 * 24 * 60 * 60 * 1000,
						url: "https://ics.calendarlabs.com/76/mm3137/US_Holidays.ics",
						color: "green",
						name: "US Holidays",
						symbol: "plane"
					},
					{
						fetchInterval: 7 * 24 * 60 * 60 * 1000,
						url: "https://calendar.google.com/calendar/icalxxx.ics",
						color: "pink",
						name: "J's calendar",
						symbol: "face-smile"
					},
					{
						fetchInterval: 7 * 24 * 60 * 60 * 1000,
						url: "https://calendar.google.com/calendar/ical/xxx.ics",
						color: "blue",
						name: "K's calendar",
						symbol: "person-digging"
					},
