Bar chart type colors not working

As in title,
only one color work on this type of chart.
Regardless of whether it is done by views settings or by php:

 foreach ($sets as $title => $records) {
      $chart_id = 'dataviz_ch' . $this->display->vid . '_'. $this->display->id . '_'. $views_dataviz_log . '_'. $set;
      $output .= '<div class="dataviz" id="' . $chart_id . '"></div>';
      $settings['chart'][$chart_id] = array(
        'data' => array(),
		'columns' => array($options['_columnLabel']),
        'chartType' => $options['type'],
        'containerId' =>  $chart_id,
        'options' => array(
          'forceIFrame' => FALSE,
          'chartArea' => $chartArea,
		 'colors' => array('#010101', '#621341'),
		  'backgroundColor' => array('fill' => '#EDEDED'),
		  'legend' => array('position' => 'right'),
          'title' => $options['_graphTitle'], //$one ? $this->display->display_title : $title,
        ),
      );
