如何使用ui-leaflet和markercluster来改变Markercluster的颜色？

Question

我必须创建一个非默认的markerCluster颜色。我检查过接口，似乎他们建议在创建后修改一个divIcon (我相信，我正在同时学习Leaflet，ui-leaflet，MarkerCluster )，如下所示：

var markers = L.markerClusterGroup({
iconCreateFunction: function(cluster) {
    return L.divIcon({ html: '<b>' + cluster.getChildCount() + '</b>' });
}
});

我填充数据的方式是在创建时，更接近于这样：

layers: {
                baselayers: {
                    osm: {
                        name: 'OpenStreetMap',
                        type: 'xyz',
                        url: 'http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',
                        layerOptions: {
                            subdomains: ['a', 'b', 'c'],
                            attribution: '&copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors',
                            continuousWorld: true
                        }
                    },
                    cycle: {
                        name: 'OpenCycleMap',
                        type: 'xyz',
                        url: 'http://{s}.tile.opencyclemap.org/cycle/{z}/{x}/{y}.png',
                        layerOptions: {
                            subdomains: ['a', 'b', 'c'],
                            attribution: '&copy; <a href="http://www.opencyclemap.org/copyright">OpenCycleMap</a> contributors - &copy; <a href="http://www.openstreetmap.org/copyright">OpenStreetMap</a> contributors',
                            continuousWorld: true
                        }
                    }
                },
                overlays: {
                    hillshade: {
                        name: 'Hillshade Europa',
                        type: 'wms',
                        url: 'http://129.206.228.72/cached/hillshade',
                        visible: true,
                        layerOptions: {
                            layers: 'europe_wms:hs_srtm_europa',
                            format: 'image/png',
                            opacity: 0.25,
                            attribution: 'Hillshade layer by GIScience http://www.osm-wms.de',
                            crs: L.CRS.EPSG900913
                        }
                    },
                    cars: {
                        name: 'Cars',
                        type: 'markercluster',
                        visible: true
                    }
                }
            },
            markers: {
                m1: {
                    lat: 42.20133,
                    lng: 2.19110,
                    layer: 'cars',
                    message: "I'm a moving car"
                },

这是我从一个类似的(分叉断开的)站点上偷来的：https://github.com/tombatossals/angular-leaflet-directive/blob/master/examples/0216-layers-overlays-markercluster-example.html，我试图添加一个单独颜色的图标属性，但没有用。当多个类型聚集在一起时，我正在尝试更改颜色。任何帮助都将不胜感激。

提前谢谢。
