My 100% Sicilian friend has blue eyes. My paternal grandfather from Naples had red hair. I had platinum blonde hair (gone now) have blue eyes but I’m only 3/4 Southern Italian. 1/4 Irish/English/scott. So my eye/hair is a legitimate mix.
Sicily has had 17 invasions over the last 3500 years. There’s bound to be some mixed races in that group. You want the truth 23 and me. It might shock you. You can be genetically from one area but culturally from another area. My genetic background is Italian,Western Asia and Northern Europe but my cultural background is hotdogs,apple pie and the New York football Giants.
