You finally released the eyes huh? Good job sir

It would go with the whole blue/white theme that the Handmaiden seems to have...
But, even assuming that Kreia is Arren Kae, there's no telling what she could have looked like. We know only that her face resembled her mother. The white hair, silver eyes and pale skin is all from Yusanis, meaning that Kae could have been a blonde, brunette, red head and the color of her eyes could vary even moreso.
That said, a blue version would be pretty cool. That, and I'd make the irises a tad bigger
