Single ion-tab color


Hello, is there a way to change only one tab icon color ? example:

<ion-tabs  >
  <ion-tab [root]="homeRoot"  tabIcon="home"   > </ion-tab>
  <ion-tab [root]="myAccountRoot"  tabIcon="person"></ion-tab>
  <ion-tab [root]="notificationsRoot"  tabIcon="notifications"> </ion-tab>//thisone
  <ion-tab (ionSelect)="logout()"  tabIcon="power"></ion-tab>

I want to set notifications tab to red and have the possibility to put it back to default color (white), or add a number or something to the icon so that it says “Hey new notification here”
