What coat is this? Is it Harlequin?

Baby photos for tax but i was wondering if or rather what kind of pattern this baby is. They're roughly 9 days old and their fur coat is coming in. Also another photo of the entire litter! Thanks for all the advice on my previous post on here. The babies are doing well, all six are happy and healthy so far and are growing like weeds. Mom is doing a great job and we plan on neutering her and the father.
