How to WP Query custom multiple custom taxonomies?

Question

Here is the way I think it should work:

$args = array(
    'post_type'         => 'item',
    'post_status'       => 'publish',
    'posts_per_page'    => -1,
    'tax_query'         => array(
        array(
            'taxonomy'  => 'color-categories',
            'field'     => 'slug',
            'terms'     => array('red', '2000'),
            'operator'  => 'AND'
        )               
    )       
);

So you query posts which are in both red and 2000 using operator AND.
