Found another... In the Caliber chapter of volume 8 Early and Late after they pulled out Excaliber.

Having a conversation like that finally helped loosen the constriction in my stomach, while my hands still hugged Excaliber, I asked Lyfa to my left,

“Lyfa, W-W-What happened to the S-Slaughter quest?”

Then, the Sylph with her pea green ponytail trailing vertically stopped screaming —— or perhaps it was a joyful shout, I have my doubts —— and looked at the medallion on her chest.

Once again, the spelling of her name indicates a fan translation, but it looks like there are 3 references to her hair being green. Also if you look at the web summaries of the Alicization Arc, there's a statement that Kirito remembers that the Orcs remember Leafa as the 'Green Swordswoman' with renown and look forward to her return even after 200 years. Of course, in that instance, the green could refer to her clothing... But I suspect it's a bit more than than.
