Geriatric White's Tree Frog

[into]

if given the choice I would have gone for a blue phase, but he desperately needed a home so here he is (and has been for a good long while).

I'm a bit confused by the whole blue phase whites thing. I have a juvenile whites, Dumper who is a bluish green (today he's grey) and my female whites, Jade ranges from green bean color to a bright yellow/green. I thought I read somewhere that the bluish ones come from Australia and the green ones come from Indonesia. My whites are clearly different in shape and color. Would my Dumper be considered a blue phase?
