How to override default behavior of select color dialog ?

I need just to select color and just to save its value into hidden input on page. It seems that if i can override behavior of "select background color button" it would be that i need.
i put this button into toolbar and analized some produced html code ... After color selection it calls something like

CKEDITOR.tools.callFunction(
     52,  // seems to be some kind of numerical ref to function
    '#001100', // color value
    'back'  // dont know what does it mean in current context, but its everywhere in color dialog 
);

How can i override that magic function №52 ?
I found CKEDITOR.tools.override(oldFunc, funcBuilder) in the documentation, but i have no idea how to use it. Can somebody explain the technics ?

ps. i'm sorry for my weak english, its not my native

Re: How to override default behavior of select color dialog

i found workaround, but it is dirty hack
i modified directly ckeditor.js adding

if(G=='back' && F!='?')m.MY_COLOR_VAR=F;return;}

to beginning of function, that in source representation defined in colorbutton/plugin.js here

...
function renderColors( panel, type, colorBoxId )
      {
         var output = [],
            colors = config.colorButton_colors.split( ',' ),
            total = colors.length + ( config.colorButton_enableMore ? 2 : 1 );

         var clickFn = CKEDITOR.tools.addFunction( function( color, type )
            {
                                      // HERE IS MY MODIFICATIONS
               if ( color == '?' )
               {
                  var  applyColorStyle = arguments.callee;
                  function onColorDialogClose( evt )
                  {

...

it is ugly and awful hack, i have no more functionality about changing backround color ... but i have defined color in MY_COLOR_VAR that exist in my ckeditor instance. it works, but i still want to know how i can do it in correct way.

ps. again sry for my weak english
