How to change the background-color of headers and footers and how to include an image to headers

How do I change the background color of the header and the footer? Also I need to change the image/ Business label how do I do that?  I have search many forums and I cant find the answer. It's a per-existing table. It's Orange now I need to change it to blue. I also cant find where my image library is. Please see attachment. Please help. Thank you.

background-color: blue !important;

}
