What am I doing wrong here... let listItems = document.querySelectorAll('#rainbow');

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

for(var i = 0; i < colors.length; i ++) { 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>
js/app.js 
let listItems = document.querySelectorAll('#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 there! You're so close here that I'm just going to give a hint. Your code is currently selecting all items that have the id of "rainbow". However, there is only one element that has that id and that's the unordered list. What you're supposed to be selecting is all list items inside the unordered list with the id "rainbow".

I think you can get it with these hints, but let me know if you're still stuck! :sparkles:

Thank you so much for the hint Jennifer, I was too much in to the 'querySelector' that I didn't read the question right. Just running it with 'querySelectorAll('li"); ' worked perfect!
