WooCommerce Cart CSS

On the cart page after adding an item to the cart from here: https://masterantioxidant.ca/product-category/masterantioxidant/ and clicking on "Calculate Shipping" the "Select a Country" text is black as well as the following option box "Select an Option" after picking "Canada" in the first box.

I would like this text to select the country and province to be white. I can't right click on it to figure out the CSS selector though.

Thanks in advance,
