Changing background color within additional info panel on product page.

Site URL: https://blueberry-frog-7egg.squarespace.com/store-2/p/country-feast-set-myd8z

Id' like to change the color of the background halfway through the additional info page on the product page.

The color should start at the gray line above the image and can expand down before the footer, I'd also like for the background to expand the entire width of the page and be in the color HEX #C7C6C7.
