Not sure what to do

I tried to look into this and I'm confused by what it wants me to do and I don't know how to proceed with it.

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];    
}
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>

On the very top line, the "listItems" needs to be given a value in addition to being declared as a variable. The "querySelectorAll" method used with a descendant selector argument might come in handy to doing this.

I seriously don't know what you talking about can you send me code example? I want to go through and understand that.

You may want to look at this answer I gave to a similar question. Just be aware that there is more than one possible solution.
