What I am getting the error "There Should be a 7 list Item "

I think something is wrong whit my loop?

js/app.js
var listItems = document.querySelectorAll("#rainbow");
var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

for(var i = 0; i < listItems.length; i += 1) {
  listItems[i].style.color = colors[i];    
}
index.html
<!DOCTYPE html>
<html>
  <head>
    <title>Rainbow!</title>
  </head>
  <body>
    <ul id="rainbow">
      <li>This should be red</li>
      <li>This should be orange</li>
      <li>This should be yellow</li>
      <li>This should be green</li>
      <li>This should be blue</li>
      <li>This should be indigo</li>
      <li>This should be violet</li>
    </ul>
    <script src="js/app.js"></script>
  </body>
</html>

You are selecting the ul not the list items. See Descendant Selector here for how to go about selecting the list items.
