I would think with a Albino BkEL, there would be no pattern. I guess there is a possibility the yellow splotches (if there are any) could turn pinkish at first.
I would be interested to see the Polar Ball as an adult. I would think it would lose a lot of that contrast. I think in this case, the Russo Lucys have a stripe and this is just accentuated here as pink.
That's a valid point. Hatchlings do tend to lose a lot of their contrast into adulthood so it's very likely that the Polar doesn't look the like it once did but hey, I've yet to actually see a more recent picture of this guy so you never know. :S
