Hi Nas Jones!

You are just missing the index for the paragraphs items.

Your code should look like this:

var section = document.querySelector('section');
var paragraphs = section.children;

for (let i = 0; i < paragraphs.length; i+= 1) {
paragraphs[i].style.color = 'blue';
}

That fixed it thank you for the help!
