I use Customify Theme from Press Maximum for a lot of my WordPress builds, and unfortunately their Documentation (lacks) some finer points on how to Edit and change the Styling of the Template.
Follow the below in order and you should not have a problem
- Customify
Change Cover Settings - Page Header
- Display Settings
- Color & Background
- Title Color
- Cover Overlay
You Can ONLY do this if you have PRO installed
- Select Layouts
- Page Header
- Scroll down to Titlebar Settings
- Click Titlebar Styling edit pencil
- Background Color – Select Colour
- Publish
