CKEditor and problems with change background color

[eluser]nahalem[/eluser]
Doesn't work, global_filtering have to FALSE. I'm trying to do this and still nothing:

Code:

//Replacing styles from the "Styles tool"  
   '.field' => array(
  
    //Creating a new style named "style 1"
    '.field' => array (
     'name'   =>  'Blue Title',
     'element'  =>  'h2',
     'background-color' => 'Yellow',
    
    '.field' => array(
      'color'  =>  'Blue',
      'font-weight'  =>  'bold',
      'background-color' => 'black'
     )
    ),    
   )
