Change colors icon Ion Toolbar

I am trying to change the color of the icons inside the toolbar but it does not work, the letters and titles if they change but the icons do not:

ion-toolbar {
    --background: var(--custom-primary);
    --color: #FFFFFF;

    ion-buttons {
        button {
            ion-icon {
                --color: #FFFFFF;
                font-size: 3rem !important;
                font-weight: bold;
            }
        }
    }
}
