Color buttons can't be customized

[Jakub Ś]

1. Insert below code on page and into contents.css

   var editor = CKEDITOR.replace( 'editor1', {		
   				//allowedContent : true,
   				colorButton_colors : 'highlight_yellow/FFFF00',
   				colorButton_backStyle : {
   					element : 'span',
   					attributes : {
   						'class' : '#(color)',
   						'element' :'#(color)'
   					}
   				}
   });
   
   
   //in contents.css
   .highlight_yellow{
   	background-color: #FFFF00;
   }
   

2. Refresh the cache.
3. Highlight the word and change its color to Yellow.

Results:

1. Witah allowedContent:true commented out once you switch to source and back, span will be removed and it shouldn't be. This part is reproducible from CKEditor 4.1.

2. You can't change this color to automatic with such configuration. This part can be reproduced from CKEditor 3.0.
