You forgot the [i].

I got the same answer as above:

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

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

I added the [i] after 'blue'...

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

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

This is incorrect, I feel maybe I'm missing adding a function first?

Please help, thanks!
