Concur. Pastel poss Het Albino X Pastel & X Het Albino.
At best you produce a Pastel Albino or Albino and prove the guy out.
At worst you produce some Pastel 50% Het Albinos.
If you go Het X Het, you still only have a 25% chance per egg of producing an Albino, so you still might end up with a clutch of normal looking offspring which would be 66% Het.
