I already preview and colors are fine but why still bummer?

app.js

let listItems = document.querySelectorAll('[id=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

<ul >
      <li id="rainbow">This should be red</li>
      <li id="rainbow">This should be orange</li>
      <li id="rainbow">This should be yellow</li>
      <li id="rainbow">This should be green</li>
      <li id="rainbow">This should be blue</li>
      <li id="rainbow">This should be indigo</li>
      <li id="rainbow">This should be violet</li>
    </ul>
index.html 
<!DOCTYPE html>
<html>
  <head>
    <title>Rainbow!</title>
  </head>
  <body>
    <ul >
      <li id="rainbow">This should be red</li>

      <li id="rainbow">This should be yellow</li>
      <li id="rainbow">This should be green</li>
      <li id="rainbow">This should be blue</li>
      <li id="rainbow">This should be indigo</li>
      <li id="rainbow">This should be violet</li>
    </ul>

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

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

in your for loop you wrote "i ++" with a space instead of "i++".
