I've made every item in this list the colour it's supposed to be and yet it's saying BuMMeR.

I've got every item to be the colour it's supposed to be, but apparently that's not god enough for this ordacioius question, which is saying "BUmMeR: DiD yOU SEleCt EvrY LiST iTEm?"

js/app.js 
var listItems = document.getElementById('rainbow');
//for(let i = 0; i < listItems.children.length; i++)
  // listItems[i] = listItems.children[i];
var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

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

Hey R Ighodaro,

What you have done is correct but the in the challenge you should include children property after selecting rainbow.

var listItems = document.getElementById('rainbow').children;
var colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

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

Hope this helps!

Why does it matter I managed to get them to appear the colours they were meant to be, the code looked exactly as it was supposed to. Thanks for your help I'm not mad at you.
