Unable to select based on rainbow ID

In Challenge Task 1 of 1 in "Javascript & the DOM", I'm trying to select multiple items based on <ul id = "rainbow"> using let listItems = document.querySelectorAll["#rainbow"];

The test responds back with Bummer! Can you point me in the right direction?

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];    
}

you are only getting the unordered list, not the list items inside. you need to modify your selector line a little to reach into the ul and return a list of the list items. you can chain method calls, like myObject.methodOne().methodTwo().

In order to get the li tags you'll have to add it your querySelectorAll call like this:

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

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

I hope this helps happy coding!

Thanks James and Brian. Feel like there should have been a way to get to the <ul> child (<li>) and don't think the video explained this well enough. Feel like I may have missed something.

Thanks again to both of you for helping so fast!
