Exclude in multicolor

[Slobork]

Issue description:

While I've overcome the similar problem with a background field, I just cannot get exclude to work on the multicolor. Please can you look where's the mistake?

Version used:

develop branch

Using theme_mods or options?

theme_mods

Code to reproduce the issue (config + field(s))

    Kirki::add_field( 'MYTHEME', array(
        'settings'    => 'link_color',
        'section'     => 'SET_SECTOION',
        'type'        => 'multicolor',
        'label'       => esc_html__( 'Links color', 'mt' ),
        'priority'    => 10,
        'choices'     => array(
            'color'   => esc_html__( 'Color',  'mt' ),
            'hover'   => esc_html__( 'Hover',  'mt' ),
            'active'  => esc_html__( 'Active', 'mt' ),
        ),
        'default'     => array(
            'color'   => '#5B9fcc',
            'hover'   => '#ccc',
            'active'  => '#ddd',
        ),
        'transport'   => 'auto',
        'output'    => array(
            array(
                'choice'    => 'color',
                'element'   => 'a',
                'property'  => 'color',
                'exclude'   => array(
                                   array(
                                       'color'  => '#5B9fcc',
                                       'hover'  => '#ccc',
                                       'active' => '#ddd'
                                   ), 
                                ),
            ),
            array(
                'choice'    => 'hover',
                'element'   => 'a:hover',
                'property'  => 'color',
            ),
            array(
                'choice'    => 'active',
                'element'   => 'a:focus',
                'property'  => 'color',
            ),
        ),
    ) );

I've tried setting the exclude option for each choice, but that didn't work as well.
Thanks!

It was a matter of sanitization.
If I use this for default:

'default'     => array(
    'color'   => '#5b9fcc',
    'hover'   => '#cccccc',
    'active'  => '#dddddd',
),

and this for exclude it works:

'exclude'   => array(
    array(
        'color'  => '#5b9fcc',
        'hover'  => '#cccccc',
        'active' => '#dddddd'
    ), 
),

However, I see that I failed to take into account cases where choice is used, so I just pushed another commit that will allow you to do this:

'output'    => array(
    array(
        'choice'    => 'color',
        'element'   => 'a',
        'property'  => 'color',
        'exclude'   => array(
            '#5b9fcc',
        ),
    ),
    array(
        'choice'    => 'hover',
        'element'   => 'a:hover',
        'property'  => 'color',
        'exclude'   => array(
            '#cccccc',
        ),
    ),
    array(
        'choice'    => 'active',
        'element'   => 'a:focus',
        'property'  => 'color',
        'exclude'   => array(
            '#dddddd',
        ),
    ),
),

In other words, if you have a choice defined, then in the exclude argument you can either use a full array of the control's value - in which case it will check if all sub-values are true and only then will it exclude it, OR you can use an array of sub-values, in which case if it's equal to one of them it will be excluded.
