更改highcharts图例页面导航按钮的颜色

Question

我在angular2中有一个带有导航按钮的angular2圆环图：默认为＃003399 图例页面导航中活动向上或向下箭头的颜色。正如高级图表的API参考中所建议的那样 - highchart api link

我必须将导航按钮的颜色从默认值更改为适合我需要的其他颜色。目前在我的代码导航中无处定义。它正在使用导航按钮的默认值。当我尝试检查当前显示的导航按钮时 - 有关如何更改导航按钮的默认颜色的任何帮助。

下面是我的代码 -

  defaults() {
        this.options = {

            title: { text: ' ' },
            colors: ['rgba(79, 162, 189, 1)', 'rgba(84, 135, 201, 1)', 'rgba(143, 185, 91, 1)', 'rgba(90, 183, 130, 1)', 'rgba(71, 195, 185, 1)', 'rgba(190, 120, 203, 1)', 'rgba(228, 211, 84, 1)', 'rgba(43, 144, 143, 1)', 'rgba(145, 232, 225, 1)'],
            chart: {
                type: 'pie',
                animation: true
            },

我选择了命名颜色，因为我很懒。六角色也在那里工作（＃ffc0cb）。
