You've used a variable called $colors but you've called $color. Also remember that arrays are zero indexed, so you're looking to pull out the item at position 1. When you call an item from an array, you'll need to use square brackets [].

Try this:

<?php

$colors = array('red', 'blue', 'green');
echo $colors[1];
