Hi @panosakris ,
Thanks for reaching out!
I understand that you would like to change the color of the add-to-cart notification that displays in the right-hand corner when adding a product to the cart, is this correct?
The pop-up that is being displayed in the right-hand corner (as per your screenshot) does not default to WooCommerce core and may be a feature or either your current theme or a plugin being used on your site.
If you know how this is being added, I’d suggest reaching out to the developers of either the theme or plugin causing this behavior, since support related to third-party themes/plugins is outside our scope of support.
On the other hand, you could check out the Mini Cart for WooCommerce extension, which allows customizing the “Add to cart” notification, as seen in this section of the extensions documentation.
WooCommerce.com offers a 30-day refund policy which you can take advantage of, allowing you to test the extension, and make sure that it is what you are looking for.
Should you have any pre-sales related questions, kindly contact us directly at WooCommerce.com → My Account → Support. You will need to create an account if you do not have one already.
Cheers!
thanks for your comments!
