How to display related data in html with Angular 7

I am new to Angular 7. I am trying to display a product's color on html side with Angular 7 but I couldn't succeed.

My tables are like below;

Product

Id

Name

Color

Id

Name

ProductColorRelation

Id

ProductId

ColorId

In product.component.ts file, product variable is declared

public product: Product;

On Product screen, I am trying to display product's colors with code below

{{ product.ProductColorRelations[0].Name }}

But it doesn't display the color's name. What am I doing wrong here?

Thanks

<div *ngFor="let product of products">

</div>
