Query Selector challenge, can't do it

as my understanding either of the following syntax should work: var listItems = getElementById('rainbow') or var listItems = querySelectorAll('#rainbow')

What am I doing wrong?

var listItems = document.querySelectorAll('#rainbow');
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>
    <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>
    <script src="js/app.js"></script>

Notice anything about the code above?

You are grabbing <ul> instead of <li>. You need an array of html elements(<li>), not a list of #rainbow. Having said that I had similar problem with this particular challenge as the instruction is a bit unclear.

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

I've remove the dote, still doesn't work. But thanks for the hint.

Cheo wanted to draw your attention to the fact that you need to grab a collection of html items, which is an array instead of just one item.

listItems[i] instead of listItems.[i]
