选择选项后，如何将 Angular Material mat-autocomplete 文本颜色更

Question

我不想更改占位符颜色，因为我已经完成了，但选择一个选项后，文本颜色仍然是黑色。

这是我的 HTML

<form *ngIf="videos">

    <mat-form-field class="search-form">

      <input type="text" placeholder="Search Gamer-Tags" aria-label="Number" matInput [formControl]="myControl"

        [matAutocomplete]="auto">

      <mat-autocomplete #auto="matAutocomplete" autoActiveFirstOption (optionSelected)='searchChange($event.option.value)'>

        <mat-option class="auto-option" *ngFor="let option of filteredOptions | async" [value]="option">

          {{option}}

        </mat-option>

      </mat-autocomplete>

    </mat-form-field>

  </form>

这是我的 SCSS

::ng-deep .mat-focused .mat-form-field-label {color: white !important;}

::ng-deep .mat-form-field-underline, ::ng-deep .mat-form-field-ripple {background-color: white !important; color: white !important }
