I've always used this code in a must-use plugin to remove the whole color schemes section:
remove_action( 'admin_color_scheme_picker', 'admin_color_scheme_picker' );
Unfortunately, with WordPress 6.0 this does not work anymore. I've found that Core's add_action( 'admin_color_...
was recently moved from default-filters.php
file to the admin-filters.php
file, but I am unsure why and how I'd have to update the above snippet to make it work again.
For a remove_action()
call to be effective, it needs to be called after the action you want to remove has been added, and before the action runs.
WordPress adds the admin_color_scheme_picker
action in admin-filters.php and then runs the action in the user-edit.php admin page template.
To remove the admin_color_scheme_picker
action right before it is called on the user profile page, you can run the remove_action()
call using the admin_head-profile.php
hook:
add_action( 'admin_head-profile.php', 'wpse_72463738_remove_admin_color_scheme_picker' );
/**
* Remove the color picker from the user profile admin page.
*/
function wpse_72463738_remove_admin_color_scheme_picker() {
remove_action( 'admin_color_scheme_picker', 'admin_color_scheme_picker' );
}
Note that the admin_head-{$hook_suffix}
hook fires in the head section for a specific admin page. In the example above replacing $hook_suffix
with profile.php
in the hook name makes it run on the user admin profile page.
