Yes, this works:

if( is_admin() ){
        add_action( 'wp_default_scripts', 'wp_default_custom_scripts' );
        function wp_default_custom_scripts( $scripts ){
                //$scripts->add( 'wp-color-picker', "/wp-admin/js/color-picker$suffix.js", array( 'iris' ), false, 1 );
                did_action( 'init' ) && $scripts->localize(
                        'wp-color-picker',
                        'wpColorPickerL10n',
                        array(
                                'clear'            => __( 'Clear' ),
                                'clearAriaLabel'   => __( 'Clear color' ),
                                'defaultString'    => __( 'Default' ),
                                'defaultAriaLabel' => __( 'Select default color' ),
                                'pick'             => __( 'Select Color' ),
                                'defaultLabel'     => __( 'Color value' ),
                        )
                );
        }
}
