This is done by opening a IntervalListWriter, then opening each interval and writing the value for that interval. In Java:

try (ModelCesiumWriter model = packet.openModelProperty()) {
	try (ColorCesiumWriter color = model.openColorProperty()) {
		try (CesiumIntervalListWriter<ColorCesiumWriter> intervals = color.openMultipleIntervals()) {
			try (ColorCesiumWriter interval = intervals.openInterval()) {
				JulianDate start = new GregorianDate(2012, 8, 4, 16, 0, 0).toJulianDate();
				JulianDate stop = new GregorianDate(2012, 8, 4, 16, 1, 0).toJulianDate();
				interval.writeInterval(start, stop);
				interval.writeRgbaf(Color.RED);
			}
			try (ColorCesiumWriter interval = intervals.openInterval()) {
				JulianDate start = new GregorianDate(2012, 8, 4, 16, 1, 0).toJulianDate();
				JulianDate stop = new GregorianDate(2012, 8, 4, 16, 2, 0).toJulianDate();
				interval.writeInterval(start, stop);
				interval.writeRgbaf(Color.GREEN);
			}
		}
	}
}

this produces:

{
  "model":{
    "color":[
      {
        "interval":"2012-08-04T16:00:00Z/2012-08-04T16:01:00Z",
        "rgbaf":[
          1,0,0,1
        ]
      },
      {
        "interval":"2012-08-04T16:01:00Z/2012-08-04T16:02:00Z",
        "rgbaf":[
          0,1,0,1
        ]
      }
    ]
  }
}
