There are 3 original sources of all modern european genes.
1. Paleolithic hunter gather peoples like Western hunter gatherer/ Ancient north eurasian / eastern hunter gatherer / etc. Theres some variety here, but they make up only maybe 5% of the genome, so its largely irrelevant.
2. Anatolian Early Neolithic Farmers. This makes up ~50-80% of the european genome depending on your region. Modern sardinians are apparently nearly 100% ENF.
3. Proto-Indo-European DNA. This can be up to 50% of DNA in some areas.
The phenotypic differences between different European groups come from having 10-20% more or less ENF vs PIE DNA. All Europeans cluster tightly together genetically, and are a distinct group from other world groups.
Your fascination with a minor aesthetic detail like hair color is not arbitrary - vision is the predominant sense that is used in humans, and we have evolved to use differences in appearance as in-group/out-group markers.
However, visually detectable differences are among the least genetic differences between different groups - differences in metabolism, immunity, central nervous system and cognition, organ function, etc are all far larger than aesthetic differences even among groups that look wildly different.
Anyhow, my point is that D&C shilling over something as inconsequential as hair color is really stupid. Two siblings can have different hair color, and are far more genetically similar than two strangers with the same hair color.
You are very closely genetically related to all europeans regardless of hair color, and are far less closely related to non-european groups. Stop pushing D&C shilling, and do something useful with your time, like a charity that distributes birth control to africa.
