Styling Wordpress error page

Question

I am trying to style the error page related to the error "This has been disabled".

This error comes up when people try to access the page https://benefacto.org/wp-admin/ .

I thought maybe because it was a link with "wp-admin" it might be related to back-end styling?

I tried styling it with my stylesheet that is enqueued on the back-end it did not work.

Is there maybe a specific stylesheet I need to enqueue to style the error?

This is the styling I am trying to apply to the page:

/* Customises the WP-Error message on the login page */
body#error-page {
    background: #9100c0 !important;
}

Here is a screenshot of the page I want to style:

The link for this page is "example.com/wp-admin"

I appreciate any help or suggestions! ^_^

Add this code on your activated theme's function.php

function my_login_custom_css() { 
?>
    <style type="text/css">
            body#error-page{
                background-color:  #9100c0;
            }
    </style>
<?php }
add_action( 'login_enqueue_scripts', 'my_login_custom_css' );
