Check with my code,
$list = $this->getRequest()->getParam('list', false);
$filter_ids = explode(",",$list);
$objectManager = \Magento\Framework\App\ObjectManager::getInstance();
$productcollection = $objectManager->create('Magento\Catalog\Model\ResourceModel\Product\CollectionFactory');
$categoryProducts = $productcollection->create()->addAttributeToSelect('*')->addAttributeToFilter(['color', 'system'],
[ array(
['in' array('attribute'=> 'color','in' => $filter_ids]$filter_ids),
['in' array('attribute'=> 'system','in' => $filter_ids]$filter_ids),
