Highend Footer Customization

I am editing my site which is using the Highend theme and I want to change the background color for the Footer to white (and the text to black). From the Dashboard I go to Appearance > Customize > Color – Footer, and change the colors accordingly. Then I “Save and Publish,” and click “Update” on the page editor view, and then preview. There is no change on the Footer.

I have had success uploading an image (via SiteOrigin Image widget) to the footer and that looks great. I’m just hoping to change the background color (at the very least).

Thanks in advance for any advise you may have.
