The yellow bleeding into the white really varies from one individual to another, I have sold a proven female years ago with little to no bleeding, than again that female was a tiger albino (genetic reduced pattern) so it may have help.
A lot of Albino and most combos will do that sadly often leaving you with a yellow snake, the best combos to that prevent that are Black Pastel Albino and Albino Pied (also there the yellow is bleeding in the saddle markings it does bleed anywhere where else leaving you with a white and yellow snake)
