Pinarbasi was Anatolian Hunter Gatherer population and they were distinct from WHGs albeit WHGs having minor influence on their genome. Pinarbasi like ancestry is higher than 40-50% in Sardinians because Anatolian Neolithic Farmer, the Mediterranean ancestry that Sardinians have is 90% Pinarbasi like and Sardinians on average being 77% ANF ( I don't recall the exact number) they will automatically end up having more Pinarbasi like effect. There may be individual Sardinians pushing 20% WHG, I personally found a Basque sample in G25 database that gets modeled with 23% WHG but that is the most WHG anyone gets modeled with throught the entire database.
Phenotype does not always equal genotype and the only WHG thing that the dude in the picture has is blue eyes and I believe even ANF had the capacity to produce people with blue eyes as did CHG.if anything, WHGs were presumed to have moderately dark skin which was darker than most west eurasian populations living today. Perhaps they were on par with saudis at that.
