Woofie, I just bought a Hawaiian from the woman at gemsandstems (your link above) and I ask her about when the babies change. Here is her answer.
Usually they stay variegated until they are removed & root themselves in a pot. Though I've had a few overgrown babies that have turned green right on the plant and sent out runners all their own while still connected to the mother plant. You will see that the babies I send to you are in the stage of turning from variegated to green. They still have a slight chartreuse green in center of the leaves.
She is really very nice and I will show pictures when her babies arrive. She seems to know quite a bit about spiders. I hope we learn something here.
