Google maps 谷歌地图群集图标文本变为蓝色

我在谷歌地图中使用以下样式实现了Markercluster。一切正常，但标记簇的文本在摆弄地图后变为蓝色。我希望文本是白色的

  styles: [{
                        height: 53,
                        url: markerIcons.clusterM1,
                        width: 53,
                        textColor: "white",
                        textDecoration: "none"
        },
                    {
                        height: 56,
                        url: markerIcons.clusterM2,
                        width: 56,
                        textColor: "white",
                        textDecoration: "none"
            },
                    {
                        height: 66,
                        url: markerIcons.clusterM3,
                        width: 66,
                        textColor: "white",
                        textDecoration: "none"
            },
                    {
                        height: 78,
                        url: markerIcons.clusterM4,
                        width: 78,
                        textColor: "white",
                        textDecoration: "none"
            },
                    {
                        height: 90,
                        url: markerIcons.clusterM5,
                        width: 90,
                        textColor: "white",
                        textDecoration: "none"
            }]
            });

这是因为它的文本变成了超链接文本，这使得文本带有下划线和蓝色

可以扩展css对象以包含超链接样式吗

{
                        height: 78,
                        url: markerIcons.clusterM4,
                        width: 78,
                        textColor: "white",
                        textDecoration: "none",
                        a.register:link { color:#FFFFFF; text-decoration:none;},
                        a.register:visited { color: #FFFFFF; text-decoration:none;},
                        a.register:hover { color: #FFFFFF; text-decoration:underline; },
                        a.register:active { color: #FFFFFF; text-decoration:none; }
            },
