DOM question, why is this not returning the values of the 'rainbow' id?

ive tried what i think is every possible solution... This is the one i think is my best guess... help me...

js/app.js
var listItems = document.getElementsByClassName('rainbow')[0];

var 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>

The element has an ID of rainbow, but not a classname of rainbow.

You could use document.getElementById() instead
