We got one of Ganziani's Pastel Het Albinos. He is a nice little guy, but probably our most tempermental currently.
Yes their is such a thing as a pastel albino. The problem with them is you really have to know what you are looking for to see it. A specific patch of faded yellow shows on the head and most people would never notice it. It also probably would not show up well in a picture. I'm betting a Super Pastel Albino would be impossible to see.
