Super Pastel X Normal = SHOULD be all Pastels, NO normals, NO Super pastels.
With that said there are a few things that could be at work here:
1) You have another gene influencing the phenotype of your "pastel" that is an Allele to pastel. (Think Crystal Ball, Superstripe, and any of the white snake complex snakes like a Lesser Mojave Leucy)
2) You have another gene influencing the phenotype of your "pastel" that is not an allele (Think Bumblebee x normal = pastels, spiders, normals, and Bumblebees)
3) That during recombination/segregation the "normal" allele was lost/discarded and the pastel allele was cloned to replace it, leaving you with a homozygous animal, where you should only have hets. This is the least likely of the three (though it does happen, if you look at Ralph Davis' breeding records from last year or the year before, he got a clown out of a clutch that should have only produced hets if i recall correctly).
Irregardless of which one, beautiful animal and can't wait to see more pics and congrats
