    private var _allColorCodes:Object;

    public function ColorLibrary() {
        init();
    }

    private function init(){
        _allColorCodes = {
            'black'     :   '000000',
            'white'     :   'FFFFFF',
            'yellow'    :   '000000'

    }

    public function exchangeColor(colors:String){
        var colorArray:Array = colors.split(',');
        for ( var i:int = 0; i < colorArray.length; i++ ) {
            _allColorCodes.getDefinitionByName(colorArray[i]);
        }

    }

}

any idea how to convert string to instance name? Thanks very much~! Strugglying here

I can´t see why you would want to do it like this, but here is a function that passes a list of colors (String) and returns hex codes (Array). If one color does not exist you will get lost in the Array. I Recommend using ColorList.RED or at least ColorManager.getColor("red").

var colorList : Array = getColorList("black,yellow");

public function getColorList(colors : String) : Array
{
    var result : Array = new Array();
    var colorArray : Array = colors.split(',');

    for(var i : int = 0; i < colorArray.length ; i++)
    {
        if(_allColorCodes[colorArray[i]])
            result.push(_allColorCodes[colorArray[i]]);
    }

    return result;
}
