I didn't realize Paradox rosys had been discovered.

"Rosy, Rubber, and Sand Boas" by R. D. Bartlett mentions it, saying that they were produced by Randy Limburg.

"In his 2004 breedings, Limburg produced a boa phase that is being termed a paradox rosy boa. Apparently this boa is mostly of albino appearance but has some patches of normal pigmentation."
