Darn, sorry that didn't help with the orange color bar. The topic images are in /modules/news/images/topics/ and you pick the image you want when you create the topic. If the image isn't already there then put what images you want there. You can upload images as well from the topic manager. Just make sure that directory is writable.
Do you have a link to your website that we can look at or is it a private site?
