How can I adjust the footer color and position on the debut theme?

Heres my page. I am on the debut theme and I would like to bring the footer color down to the black line in the middle of the footer between my quick links and accepted payment options.

If that’s not possible can you help me bring the quick links as far down the page as possible?

margin-bottom: 0;

.site-footer__hr {
margin: 19px 0 20px 0;
