What is the best way to retrieve the navbar css property from a different component in Angular?

I currently have a navbar set up with the following code:

<mdb-navbar SideClass="navbar fixed-top navbar-toggleable-md navbar-expand-lg scrolling-navbar py-0 navbar-dark lunada-gradient" [containerInside]="false">

Is there a way for me to modify the lunada-gradient property from a different component, specifically the customizer in this case? Here's an example of how it can be done:

<div class="col">
    <span class="deep-space-gradient d-block rounded-circle" style="width:20px; height:20px;"
        data-bg-color="deep-space-gradient" [ngClass]="{'selected': selectedBgColor === 'deep-space-gradient'}" 
        (click)="changeNavbarBgColor('deep-space-gradient')">
  </span>
</div>  

The Customizer Component:

 selectedBgColor: string = 'lunada';selectedBgColor: string = 'lunada';

  options = {
    bgColor: 'lunada-gradient',
    layout: 'light'
  };

  constructor(
    private layoutService: LayoutService,
  ) {
    this.layoutSub = layoutService.customizerChangeEmitted$.subscribe(
      options => {
        if (options) {
          if (options.bgColor) {
            this.selectedBgColor = options.bgColor;
          }
        }
      }
    );
  }

  changeNavbarBgColor(color) {
    this.selectedBgColor = color;
    this.options.bgColor = color;

    this.layoutService.emitCustomizerChange(this.options);
  }

  options = {
    bgColor: 'lunada-gradient',
    layout: 'light'
  };

 changeNavbarBgColor(color) {
    this.selectedBgColor = color;
    this.options.bgColor = color;
    this.layoutService.emitCustomizerChange(this.options);
  }

When you want to alter the CSS of a different component, using ::ng-deep in your own component is one option. However, it's important to proceed with caution as things can easily get messy.

Here's a straightforward example of how this can be done:

::ng-deep mdb-navbar {
  background-color: red;
}
