Dream Way Template/SG Window

If you look at https://www.beautifulsoulblessings.com and scroll to the bottom, you will see an incredibly BLUE background in the footer section. I need to change that color to a more muted eggplant type color as you see on the GoFundMe widget and the newsletter widget. #7361a0

I went through the customization and did not see a place in the color options to change this. How would I do this?

thank you,
Kristi
