It's a different line of albino. A little different color that does very nice things to other morphs when combined. Look up the Lavender Albino Pied. Also called the DREAMSICLE ball. It's on my dream list.
The lavenders have a purple tint to their white areas. Plus one is t+ albino and the other is t- meaning that if you bred them together, you would just get double hets. People consider them more valuable because they are "purple" and yellow. Value is all in the colors.
