Red hair is strongly associated with Irish people on account of how common it is here. Less well known, at least outside the island, is that the Irish language has one word, rua, for the red of red hair and another word, dearg, for more prototypically red hues.*
Every language carves up the colour spectrum differently, and it can take children a while to figure it all out in the culture they happen to be raised in. Even as an adult I still discover nuances, one of which appears in Robert Bernen’s story ‘The Yellow Dog’ in his collection Tales from the Blue Stacks (1978).
The narrator is visiting a local farmer with a view to getting a sheep dog:
‘Is this the dog?, I asked.
His fur was that light rust or orange colour we talk of as red hair, and so often associate with Ireland. At home, in America, I would have called him a brown dog. Here in the Donegal hills, I found out later, he was a yellow dog. As I watched him squirming towards me, his belly so low to the ground it seemed as if he was almost afraid to stand at his real height, with that look in his eyes of hope filled with fear, I thought to myself, ‘At least he’ll be friendly.’
‘Will he make a good sheep dog?’ I asked.
‘The best,’ Mickey Paddy answered.
