段按钮不变色

Question

我在项目中使用带有标签和滑动段的自定义图标。看起来像这样： 我正在尝试所有方式来选择它，将图标颜色更改为我想要的颜色。当我单击时，如果按住单击，它会变暗，因此我相信可以更改，但是我不知道自己在做什么错。如果有人知道如何帮助我，请问我已经很久了，我无法获得答案。 meu codigo .TS

this.SwipedTabsIndicator = document.getElementById("indicator");
}
selectTab(index) {    
this.SwipedTabsIndicator.style.webkitTransform = 'translate3d('+ 
(100*index)+'%,0,0)';
this.SwipedTabsSlider.slideTo(index, 500);

updateIndicatorPosition() {
  // this condition is to avoid passing to incorrect index
