Generate random number and add Class to the body of the Wordpress login page

I have a problem that is simple and straight forward, but I have no idea what I'm doing wrong.

The function is simple, I want to add a class inside the Body in the login page of Wordpress, I can do that, but I also want to update the page to generate a random number to complement the class. >

Example: when accessing the page and generating a random class, let's say it is "bg_color_2", when updating the page the value changes to another random number and let's say "bg_color_4".

The function I'm using is this one, but it's not working.

function login_classes( $classes) {
    $classes[] = 'bg_color_'; // essa e a class
    $value = rand(1,5); // aqui e gerado meu numero aleatório até 5
    return $classes, $value; / onde deve retornar os valores que fique "bg_color_4"
}
add_filter( 'login_body_class', 'login_classes' );

I can do it another way, the problem and that I have to edit the wp-login.php of Wordpress and add within the class of the body this function:

bg_color_<?php echo rand(1,5); ?>

And of course this is not an alternative, even because you should never change Wordpress files without running the risk of losing them when you upgrade.

You need to concatenate the value and add it in $ classes:

function login_classes($classes) {
    $classes[] = 'bg_color_' . rand(1,5);
    return $classes;
}
add_filter( 'login_body_class', 'login_classes' );
