How does $newColor.click() able to select the new color?

I have difficulty understanding how it works. I understand that handler from first click event is called, but why it's called? I found hard to understand how this two is connected.

Since you created this earlier :

$('.controls ul').on("click", "li", function(){
  $(this).addClass('selected');
  $(this).siblings().removeClass('selected');
  color = $(this).css("background-color");
});

And the $newColor variable is equal to an li from this unordered list, when you trigger the click event on it, the 'selected' class will be added to it.

Or put even more simply, that new little colored circle your adding to the page, it will be "selected by default".

As apposed to you then having to "click" on it once you have added the newly created color option to the menu.
