How can I change the color of navbar-toggler in angular? My navbar is totally white so navbar-toggler can't be seen in mobile. I use below setting where navbar-toggler is embedded internally so I can't access the code to modify it.

<header class="h-100">
    <mdb-navbar SideClass="navbar fixed-top navbar-expand-lg navbar-dark white scrolling-navbar intro-fixed-nav"
[containerInside]="true">
    <mdb-navbar-brand>
      <a class="logo navbar-brand" [routerLink]="['']">
         <img src="/src/assets/images/logo2.png">
      </a>
    </mdb-navbar-brand>
</header>

How can I change the color please?! Here's the image for your reference.
