Header background color and image

[CFN-1]

I don't remember how I set the header image and figured out what the color code for the header background is.

Will someone please refresh my memory?

I remember that the Header image was pretty easy to set, I just don't remember where it was in the ACP.

I want to make a new image for it and I have to figure out the image background color too so that it matches the header color.

Thanks!
