Woocommerce Product has been added to cart.

How do I change the color of the ‘product has been added to cart pop up in woo commerce?

I have tried these suggested solutions.

Thanks!

#header_main .added_to_cart_notification { background-color: black; color: white!important; }

#header_main .added_to_cart_notification * { color: white!important; }

#top #wrap_all div.woocommerce-message {
border-color: black;
background-color: darkgray;
color: white;
}

#top div.woocommerce-message a.button {
color: #fff!important;
background: rgba(0,0,0,0.2)!important;
}
