why are some colours commonly found as surnames (white, brown, green) but not others (red, blue, yellow)

Question

And furthermore how does language play a part – I know red (rojas/rossi) is a Spanish and Italian surname but not English

In: 2480

Answer 1

In european cultures yellow may not be commonly kept as a last name due to it’s association with cowardice. Maybe gold, brass, or straw could be used or blonde.

Edit: Apparently not true for German. May only be an english thing.
