title: how to extend options of a jquery plugin with an array
body: <p>I am writing a jQuery plugin. There are some default options and I can change them on HTML, but how can I change  an option if it consists of an array?</p>
  
  <p>Here is the code in plugin:</p>
  
  <pre><code>(function($){    
      $.fn.extend({  
          aniTag: function(options) {     
              var defaults = {
                  radius: 25,
                  defaultradius: 0,
                  enableTilt: true,
                  tilt : 20,
                  random : true, 
                  randomMax : 25 ,
              };
  
              var colors = new Array('4AC7ED', 'FDC015', '9F78EC', 'F25C33');         
  
              var options = $.extend(defaults, options); 
  
              return this.each(function() {                
                  var o = options;
                  //some stuff
              });
          }
      });  
  })(jQuery);
  </code></pre>
  
  <p>Here is the html usage:</p>
  
  <pre><code>&lt;script type="text/javascript"&gt;
      $(document).ready(function() {
          $('.tags').aniTag({enableTilt: false});
      });
  &lt;/script&gt;
  </code></pre>
  
  <p>As you can see I can change <code>enableTilt</code> option. What I need to do is to change the values in the <code>color</code> array. Yes, I know I need to put that array in <code>defaults</code> var, but I don't know how to do it.</p>
