I would have went with "alabaster" personally, as that is a real word that describes a white translucent object(gypsum rock typically).
I guess you combined the two words albino and translucent together,..correct?
I think "Albescent" is going to be very confusing down the road, and even far more dificult to understand or say correctly for some too. But hey, they are obviously your snakes to do what you want with.
When many people hear the word "alabaster", it immediately paints an accurate mental picture of a particular white translucent look that something has.
Albescent(for me at least) leaves me thinking....what the hell????
Now I'm quite sure your intent is to have people going.......huh????, so they check further into your animal, but it might just do the opposite to whatever degree too.
In my opinion it isn't always about having a really weird bizarre name, but having the name make some good sense at the same time really.
Even though you hear the term alabaster being used once in a great while in the Ball Python hobby for the "Ivory's", it in no way can be confusing in the case of your floridana, it just won't happen.
Anyway, you could call it "joint compound" brooks, or too as far as I'm concerned, and that would also make people go huh??? too if that's what is more important..LOL!
just my opinion on it, and feel free to disregard it too..LOL!, but it seems to me you were even mentioning about keeping some form of consistent uniformity to mutation in the hobby just a little while ago. This would be a perfect time to do just that in my opinion.
But hey, if a few got on here and said "albescent" is better, by all means go with that.
