I have created a function addElements() which changes an image, background color of the body and text color of a p tag. Now when I run the following code, the image changes at the setInterval infinetely but the colors do not change even once.

function addElements() {
  var img = document.getElementById('img');
  var image = images[Math.floor(Math.random() * images.length)];
  img.src = image;

  var name = document.getElementById('name');
  var color = colors = colors[Math.floor(Math.random() * colors.length)];
  document.body.style.backgroundColor = color;
  name.setAttribute('color', color);
};

window.addEventListener('load', setInterval(addElements, 4321));
