You did not provide URL of your site, so the next code will work for you only in case the settings are the same to this demo – https://xstore.8theme.com/cart/, next time provide the URL of your site 🙂
Change the previous code to:
.et_b_header-cart .et-cart-progress .et_cart-progress-bar::-webkit-progress-value,
.woocommerce-cart .et-cart-progress .et_cart-progress-bar::-webkit-progress-value { background: #d8bc7f; }
