Dope challenge! Why does array of 3 elements created by array() function has 1, 2, 3 indexes not 0, 1, 2? Made me stuck

Please fix it

index.php 
<?php

$colors = array("Red","Green","Blue");
array_unshift($colors, 'Yellow');
$colors[]='Black';
//add modifications below this line
$colors[0]='Magenta';
$colors[2]='Cyan';

Here’s a hint: after adding ‘yellow’ and ‘black’ to the array, the array looks like this:

array(
  [0] => 'Yellow',
  [1] => 'Red',
  [2] => 'Green',
  [3] => 'Blue',
  [4] => 'Black',
)

Took me a while to figure this one out also but yellow is the start of the array
