How can the condition be reduced to one line?

I set the condition like this:

<mat-chip-list>
    <mat-chip color="accent" *ngIf="letter.status == 'Completed'" selected>
        {{ letter.status }}
    </mat-chip>
    <mat-chip color="warn" *ngIf="letter.status == 'In Work'" selected>
        {{letter.status }}
    </mat-chip>
</mat-chip-list>

Is it possible to reduced it down so it looks something like this:

<mat-chip color="letter.status == 'Completed' ? accent : warn" selected>
    {{ letter.status }}
</mat-chip>

@Input() color: ThemePalette Theme color palette for the component.

color is an input property

color="accent" static
[color]="expr ? 'accent' : 'warn'" dynamic

<mat-chip-list>
  <mat-chip
    [color]="letter.status == 'Completed' ? 'accent' : 'warn'"
    selected
    selected
  >
    {{ letter.status }}
  </mat-chip>
</mat-chip-list>
