As promised, here are a few pictures of the Ivories that I recently hatched out. This is after their first shed. The pairing was my Orangebelly (who has sired some Graphite Ivories) to an Orangebelly from AC Reptiles (sired by an Ultra Ivory).
Your Ivories have different head markings and the dorsal stripe shows some changes (especially the brighter yellow), so I still think you have 1 Pastel Ivory and 2 Chocolate Pastel Ivories.
