Glad to help. I would recommend, if you haven’t already, to make a child theme just because if you update the parent (or regular theme) you may loose the changes.
There are lots of resource out there on that topic too.
The idea is the same though.
Cheers!
What kind of header would you like to put there? Just static info, another menu, a post type, an image, or something else?
You might be able to edit it trough the theme settings like you say, but some themes don’t give you that option necessarily. One way to change the color (I assume you want to change the large gray bar area) is to edit the style.css file. If that is the case then use this code
.site-header {
background: #FFFFFF;
}
The “#FFFFFF” is hexadecimal color which is where you change the color of the bar.
The best way to do it is through a child theme but if you have more questions just ask.
Hopefully this helped.
