Background color on My Account page

Hello,

I’m using Storefront on my websites and then the Boutique child theme in 2 others.

I’ve changed the header and footer color to blue on the Customizer, and after that the background color on the My Account page became also blue, making difficult for customers to read the fields. I mean the page where customers fill out the details: address, phone number etc.

On the stores using Boutique child theme i changed the header and footer colors to red and the same happens, but in this case the My Account page just displays a thin red line, not a full red background.

All works fine with other colors.

Is there some CSS trick to keep the original background color on that page?

Thanks in advance.
