Change body background color in Services Section

Hi,
How can I change the body background of the services section?

Without background (means white) the black square containing the body text is not visible, BUT, when I try to put a background picture, the black square around the text is always visible. How can I change the color? or how can I make it INVISIBLE? I cannot find this option anywhere :confused:

Let mw know how to change it please,
thanks in advance

David.
