Using my browser inspector, I found this css active on your header:
.header__page-title.color {
background: #222222;
}
So login to your website as administrator select the customizer > additional css, and customize your css like this:
.header__page-title.color {
background: #202050;
}
The theme in use looks like a custom theme, right? I could be wrong but this class name header__page-title color reservation indicates that it might has color option. See to it that this theme has built-in option to change header color or not, look under Customizer.
Thank you so much Ross! That worked great!
Paul–I wish they had set it up to be more user-friendly but they did not. It wasn’t in Customizer. But Ross’s idea worked 🙂
Maybe I’ll try to figure out how to make everything work in the customizer so it’s easier to change things down the road.
