Promotion headline color issue

Hi, The site in developmwnt is here. I have a widget placed in the 'promotion headline right', and at some point I gave it a custom background color. Now I'd like to change the background color, but I don't find the current color in the Customizer and when I put the desitred color into the field for the background for that section nothing happens. When I look at the area for 'custom menu' I don't see the current colors there either. I think I added these before the theme was upgraded to pro. I find it hard to believe that I need to revert to the free version to be able to change the colors but that is what it's beginning to seem like. Help! Thank you
