The for loop cycles over list items and applies a color to each item using the values stored in the colors array. For ex

var listItems; var colors = [ "#C2272D", "#F8931F", "#FFFF01", "#009245", "#0193D9", "#0C04ED", "#612F90" ];

listItems = document.querySelectorAll("#rainbow");

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

If the list items have a class of rainbow it should be listItems = document.querySelectorAll(".rainbow"); and if you want to have a different color for each item it should be listItems[i].style.color = colors[i]; That will work if the colors array is the same length or shorter "listItems"
