It's not, the point was that generally speaking Sugars tend to get really whacked out with additional genes thrown in the mix.
And that Pewter Calico is a Black Pastel Pewter Calico, and Calicos aren't nearly as reactive as Sugar are.
Like I said the Pewter Sugar is most likely what you say it is but if that Cinny Sugar really is a Cinny Sugar, then I know that I will not be perusing the Black Pastel Sugar project.
Edit: Briz, I don't see a picture mate.
