The collection should contain all list items in the <ul> element with the ID of rainbow?

no idea The collection should contain all list items in the <ul> element with the ID of rainbow.

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

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

<!DOCTYPE html>

    <title>Rainbow!</title>
  </head>
  <body>
    <ul id="rainbow">
      <li>This should be red</li>
      <li>This should be orange</li>

Hey Ernest Booth,

You should select <ul> element with the id of rainbow and its children <li> using querySelectorAll() method and store in a listItems variable:

var listItems = document.querySelectorAll('#rainbow li');

var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

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

Hope this helps!
