How do you say fair hair in Irish?

There isn't one single perfect translation for "fair hair" in Irish, as the best choice depends on the shade of fair. Here are a few options:

* Gruaig fhéir: This translates literally to "hair of grass" and is a good option for light blonde hair.

* Gruaig óir: This means "hair of gold" and is suitable for a golden blonde.

* Gruaig bán: This means "white hair," so it's only appropriate for very light blonde or grey/white hair.
