A super pastel with an albino will still not produce albino, because only one parent carries the gene. BOTH parents must carry at least one copy of albino to produce albino babies.

You can either breed two het albinos (or super pastel het albino with a het albino, makes no difference) to get 25% albino.

Or you can breed a super pastel het albino with an albino to get pastel 50% albino.

an albino super pastel bred to an albino will produce 100% pastel albinos.
