If depigmentation is due neolithic lifestyle, why are they most present in cromagnoid types?

[Sacrificed Ram]

Neolithics were mediterraneans, but we tend to see blond hair, blue eyes, fair skin in cromagnoid (upper paleolithic) types. Am I wrong about it?

Evidently that is a bullshit theory that will be debunked in the near future like so many theories have been debunked in recent years. Depigmentation is not consequence of neolithic lifestyle but it is rather gracilization that is.
