Got myself DNA tested. I seem to have a lot of Hunter-Gatherer heritage.

Not at all like me. Skin colour got lighter for Britons when we got less fresh meat, which is a good source of Vitamin D.

The maternal line is that of the West Asian farmers who changed all Europe.
The paternal line comes from the metal-age invaders.
Interesting to know. A record of past conquests.
I’ve done a blog about this: Europe’s Brutal Prehistory.
