Imagine there was a society in which blue eyed people are referred to with blee/bler pronouns, and green eyed people are referred to with glee/gler pronouns, and one day someone from that society saw a brown eyed person and had no idea whether to categorise them as blee/bler or glee/gler
In the Stormlight books by Sanderson, society is split based on eye color; bright eyed vs dark eyed. Bright eyed people are called Brightness or Brightlord. Not exaclty the same as what you said, but it is an interesting society based on eye color.
