You can also name the collection views outlets differently (without subclassing):

@IBOutlet weak var collectionView: UICollectionView!

@IBOutlet weak var SecondCollectioView: UICollectionView!

method:

func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
    let cell = collectionView.dequeueReusableCell(withReuseIdentifier: "customCell", for: indexPath) as UICollectionViewCell

    if(collectionView == self.SecondCollectioView) {
        cell.backgroundColor = UIColor.black
    } else {
         cell.backgroundColor = self.randomColor()
    }

    return cell;
}

This is will be an another way.
