WordPress Multisite - Different admin theme on different site

Question

I want to set different color on the dashboard of each site (in my multisite). For example the first site is based on the user's preference, but the second one always use Midnight theme.

Is there a way to set this in functions.php?

Thanks

Just found it on other's question. Put this on functions.php.

add_filter('get_user_option_admin_color', 'change_admin_color');
function change_admin_color($result) {
  if(get_current_blog_id() === 2) {
    return 'midnight';
  }
  else {
    return $result;
  }
}
