        color="#2D2D2D";
    return this.each(
        function(){     
            var input=$(this);
            var defaultColor=input.css("color");
            map[map.length]={text:text,obj:input,DefaultColor:defaultColor,WatermarkColor:color};
            function clearMessage(){
                if(input.val()==text)
                    input.val("");

fn is a shortcut to prototype that jQuery sets up. WatermarkColor is whatever color is entered into the Watermark function, or it defaults to #2D2D2D.
