Hello! Actually the ul has an id = #rainbow and not a class .rainbow

The code below should be ok

let listItems=document.querySelectorAll('#rainbow li');
const colors = ["#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90"];

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