Hey Ammar,

You're close. With your querySelectorAll, make sure to select all list items inside of the unordered list with the ID of rainbow.

let listItems = document.querySelectorAll("#rainbow li");

Jacob Proffer added element ul li?

Hey Ammar,

What are you stuck on?

Jacob Proffer I get the error and error is out of this world for me javascript There was an error with your code: TypeError: 'undefined' is not an object (evaluating 'listItems[i].style')

Your Javascript should look like this:

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

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