I apologise if this has been asked before. I searched, but if my search wasn't hard enough, sorry! The issue is that I have variable width enabled so it will fit to the user's browser width. However, in most cases the width will be greater than the header image's width, so the background colour can be seen to the left and the right. This in itself is inevitable and not a problem, but I'd like to know how I can change the colour.

Instead of the red you see at the left and right of the banner, I'd like it to be the blue you see at the page navigation at the top.
Thanks!
