What is the Gaelic word for auburn?

Answer 1

In Scots Gaelic auburn (the hair colour) is ruadh(pronounced ROO-ugh).

In Irish Gaelic the word is Órdhonn.

In Gaelic, hair colour is often used as a descriptive nickname to distinguish people with the same first name. So auburn-haired Mary would be Màiri Ruadh, and fair-haired Mary would be Màiri Bhàn. A lot of people will have heard of Raib Ruadh -- in English, his name became Rob Roy.
