Glauce

Glauce was another name (or perhaps the real name) of Creusa, the daughter of king Creon of Corinth. It was also the name of the daughter of king Cychreus of Salamis, who was the first wife of Telamon.

It appears to derive from glaucos, 'gleaming', 'bright' and thus be a kind of 'green light' name for a propitious future. (As a colour, glaucos did actually mean 'pale green'.) However, glaucos also means 'grey-eyed' and even sometimes 'blue-eyed', so perhaps Glauce was just that.
