Bummer: Make sure that you're applying the correct color to each list item

Dear All, I am using this code const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#745CBF", "#C724B1"]; let listItems = document.querySelector('ul').getElementsByTagName('li');

for (let i = 0; i < colors.length; i++) { listItems[i].style.color = colors[i]; } I do not know why it should not work, I checked the colour names and they should be correct. Thanks in advance, Giacomo

app.js 
const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#745CBF", "#C724B1"];
let listItems = document.querySelector('ul').getElementsByTagName('li');

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

Hey there Giacomo Zanin ! 👋

The code that you wrote is perfect! The issue is, it seems the colors in your colors array have been changed. So the backend of the challenge was looking for specific colors in specific places and it wasn't getting it. You'll just need to paste in what was there when originally opening the challenge.

const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];
