Customize DIVI Project Page

The IDOL Portfolio WordPress template has "regular" pages and it has "project" pages.  The project pages are formatted to make a nice portfolio for your work.  The page template has a header image with a phone and a pen.  

Obviously you probably don't want that image for your portfolio. The challenge is finding where to change it - or remove the image and use a solid color.  This page will help you get to the right place - step 6 is to remove the image, step 7a is to choose a new background image, step 7b is to set a solid background color.
