duine gorm = black person in Irish
duine geal = white person.
That is in relation to persons, in relation to chromatic colour ‘gorm’ means blue and ‘geal’ means bright/light
Which is perhaps slightly interesting. People have speculated that the perception of colours evolved slowly and that the Homeric trope ‘wine-dark sea’ is an indication of this, but why shouldn’t there be a special word for a certain type of deep sea on a cloudy day that departs from the usual chromatic suggestion of wine red which of course it’s not any more than the ancient Celts thought that Negroes were the same colour as the sea.
