European (Europid) pigmentation spectrum

[Lutiferre]

What basic spectrum is there for pigmentation levels in Europeans and European types, before we can talk of admixture or non-native input?

Obviously there is no limit for depigmentation, since it is characteristic of European civilizations more than any other, so the spectrum must be defined towards the other end, of heavy pigmentation.

In this regard I find certain Indians to be interesting, because some of them present Caucasoid/Europoid types, yet possess heavy pigmentation, as heavy as sub-Saharan Negroid Africans. Others possess pigmentation levels that are more comparable to most Europeans, and either mixed or completely Cacausoid/Europoid traits.

However, I am not talking about just any Europoid/Caucasoid type, but native Europeans. Unlike Indians, there is not as much heterogeneity in pigmentation - sure, there is heterogeneity, but not so much that you will generally consider someone of heavy, Negroid pigmentation level to be purely European - whereas it can go down to complete melanin deficiency and the person can be a native European.

Imagine that the persons had relatively Europoid/Caucasoid traits.




Would you seriously consider whether they are unmixed? My point with this is that this is generally not possible for Europeans. There is a limit to how high pigmentation levels a native European can have.

So how is this limit defined, and has any such attempt been made?
If anyone wishes to, I also welcome you to contest my assertion that unmixed Europeans cannot posses the pigmentation levels of most sub-Saharan Africans.

I guess it is impossible to to define precisely the level maximum of pigmentation for Europids (because pigmentation level is continuous, not discrete). Rather it always becomes obvious from observing a ceratin person if his pigmentation is within the Europid spectrum or not.

Personally, I have never seen any indigenous with a pigmentation such as the one of a sub Saharan. If it was possible, we would have the opportunity to come across a few of them.
