Stuck on this JS challenge

In the previous lesson, we learn how to target CSS elements with JS using the document.querySelector & document.querySelectorAll tags however in this code challenge when we have to target the 'ul' with the id 'rainbow', this doesn't work.

Does anyone have a solution to this?

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

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

Hi

You are very close, you need to select li not ul and rainbow is an ID not a class

let listItems = document.querySelectorAll("#rainbow li");
