I need to use this mat-button in Angular project, how can I usee customized color instead of accent, primary, etc.

<button (click)="gotoDashboardHome()" mat-raised-button color="accent" class="centered-button">
            <mat-icon>reply</mat-icon>
            <span class="button-text">Back</span>
        </button>

.centered-button {
  display: flex;
  align-items: center;
  justify-content: center;
  padding: 8px 16px;
}
 
.button-text {
  margin-left: 5px;
  font-size: 14px;
}
