Magento 2 layered navigation attribute option sort by name not number of products

Question

My theme is child of magento blank. On default magento 2 layered navigation sort labels of attribute in layered navigation by Count number of products that exist with this attribute.

I need to change this alphabetically sort order.

Example: Colours: Red (10) Blue (3) Yellow (2) Change to: Blue (3) Red (10) Yellow (2)

Where should I look? In module_layered_navigation? or Magento\Framework\Data\OptionSourceInterface? or somwhere else?

I found this in vendor/magento/module-catalog/Model/Layer/Filter/AbstractFilter.php

 * Create filter item object
 *
 * @param string $label
 * @param mixed $value
 * @param int $count
 * @return \Magento\Catalog\Model\Layer\Filter\Item
 */
protected function _createItem($label, $value, $count = 0)
{
 return $this->_filterItemFactory->create()
 ->setFilter($this)
 ->setLabel($label)
 ->setValue($value)
 ->setCount($count);
}

Maybe I could add somewhere usort:

usort($this, function($a, $b) {
if($a['order']==$b['order']) return 0;
return $a['order'] < $b['order']?1:-1;

});
