How to change the initial colors of bootstrap 4?

I am trying to change both the background and the font color in the bootstrap 4 dropdown list.

I tried to use

.nav.nav-tabs > li.dropdown.active.open > a, 
.nav.nav-tabs > li.dropdown.active.open > ul.dropdown-menu a:hover,
.nav.nav-tabs > li.dropdown.open > a, 
.nav.nav-tabs > li.dropdown.open > ul.dropdown-menu a:hover
{
  color: #fff;
  background-color: #b91773;
  border-color: #fff;
}

But that is not too good for me. Here is my HTML:

      <li class="nav-item dropdown">
        <a class="nav-link dropdown-toggle" href="http://example.com" id="navbarDropdownMenuLink" data-toggle="dropdown" aria-haspopup="true"
          aria-expanded="false">
  Dropdown link
</a>
        <div class="dropdown-menu" aria-labelledby="navbarDropdownMenuLink">
          <a class="dropdown-item" href="#">Action</a>
          <a class="dropdown-item" href="#">Another action</a>
          <a class="dropdown-item" href="#">Something else here</a>
        </div>
      </li>

, _custom.scss :

@import "~bootstrap/scss/functions";
@import "~bootstrap/scss/variables";

// Add your custom variables here

@import "~bootstrap/scss/bootstrap";
