To get your memory jogging if it needs it, they were blue eyed, plaid wearing 3,000 year old mummies found in Central Asia.
We know by the age they weren't Celtic (Gaelic) in the classical Roman (Greco) sense, but maybe Pictish?
Chinee... if I remember correctly.
I venture to guess, you cannot tell what color a mummy's eyes were. Hair yes, eyes no.
