If you go into your where all your files are kept, find the yellow.css file which is included in the templates file under ‘Colors’ then ‘yellow.css
It appears that line 108 of Yellow.css is where you would make the change…BUT…
the label (Your’s says 2009 Chargers Girls) is actually an image. The surrounding of the yellow bar is the #111111 grey color. You would have to copy that image into something like photoshop and colour the outside area the color you want.
The image file is line 122 of yellow.css. Just make sure that you upload the image to the same place that the default one is. I would name the new image something slightly different and make sure to change the name in the yellow.css file to match!
BTW — I am fairly new to Joomla, and the single most important thing I did was change to Firefox browser AND DOWNLOAD FIREBUG. It is the easiest, most powerful tool I have used to help understand where to make changes to my site.
**Lastly, I have a question for you. The Chargers logo on your site — how did you achieve puttin the image into the backgound without it affecting your module positions so that it sits behind the menu, etc? I’ve been trying to do something similar on my site for a couple days.
