HOW TO CHANGE [CODE][/CODE] BACKGROUND?

hello,
I installed a theme which gives all texts white, but when I use

Code:

text

the background and text are white, so I can not read! I tried with colours managment but there is no code background edit!

I opened css and found :

Code:

dl.codebox {
   margin: 8px;
   }
.codebox dt {
   display: block;
   padding: 3px;
   background-image: url('http://2img.net/i/fa/invision/css_img_code.gif');
   background-repeat: no-repeat;
   background-position: top right;
   text-transform: uppercase;
   font-weight: bold;
   }
* html .codebox dt {
   zoom: 1;
   }
.codebox dd {
   padding: 5px;
   font-family: Courier,'CourierNew',sans-serif;
   white-space: pre;
   overflow: auto;
   max-height: 200px;
   }
* html .codebox dd {
   height: 200px;
   }


I think here somewhere I can edit the background color of [code]

but I can't even edit it!
I would be thankful for the help
