Change color seat

Can someone help me how to change the color and maintain it, my problem is when it goes to the next page, what was enabled is lost and it is not maintained

html
<ion-icon

              *ngFor="let seats of ReservasData;  let i = index;"

              class="cls-icon"

              [ngClass]="{'cls-icon1':seats.estado=='False','active':seats.estado=='True'}"

              src="../../../assets/img/icons/{{seats.img}}"

              (click)="openUpdate(seats,seats.estado,seats.id,seats.price)"

            ></ion-icon>

>
ts.
openUpdate(item, state, id, precio) {

    if (state == "ocupado") {

      console.log("Lo sentimos está ocupado");

    } else if (state == "space") {

      console.log("no hay nada");

    } else if (state == "chofer") {

      console.log("chofer");

    } else {

      item.estado = !item.estado;

}
.scss
.cls-icon {

              color: black;

              &.active {

                color: green;

              }

              &.inactive {

                color: black;

              }

            }
