My code is working but it keeps saying I'm getting the answer wrong and won't let me continue

here's my code:

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

for(var i = 0; i < colors.length; i ++) { listItems.children[i].style.color = colors[i];
}

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

for(var i = 0; i < colors.length; i ++) {
  listItems.children[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>

The instructions state 'Complete the code by setting the variable listItems to refer to a collection.' Your variable refers to a single element.

Yeah, I eventually caught that and took the .children off of listItems in the for loop and added it to the global variable listItems. Thanks!
