title: Change the color of the upward arrow on an open dropdown-menu
body: <p>I'm working with twitter bootstrap 2.0.1</p>
  
  <p>I'm trying to change the color of the dropdown-menu.</p>
  
  <p>I have managed to change the color of the container that is comming down itself, however I can't seem the find where the arrow is comming from.</p>
  
  <p>Anyone know where I can find the code where the arrow comes from (and how to change it's color)?</p>
