Why do ads show up in different color backgrounds?

[ncangler]

I am curious why multiple ads in my classifieds show up with a white background then others show up with a dark blue background. If they alternated it would make sense but there will be several with white then one or more with dark blue. Can someone tell me how to make them all the white background? I could not upload a picture for some reason so here is a link so you can see what I'm referring to:

Try adding this style class to your vb stylesheets

.yellow { color: #FF00000; }
