Javascript and the DOM challenge Task 1/1

// Complete the challenge by writing JavaScript below const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

const listItems = document.getElementsByTagName('ul');

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

I add const listItems = document.getElementsByTagName('ul'); but its not working. Not sure why?

app.js 
// Complete the challenge by writing JavaScript below
const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];
const listItems = document.getElementsByTagName('ul');

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

You're close, but the tag 'ul' refers to the outer body of the list. To select the collection of list items within it, you need to use the tag 'li' instead
