You are right a black pastel is close to the cinnimon pastel, now reffered to as a cinnimon, the pastel reference has been dropped with the cinnimon..no pastel gene is present..as far as I am aware..a black pewter is a bp x pastel..the enchi is the same, reffered to as an enchi pastel but should really be called an enchi as no pastel gene is present unless mated with the pastel gene then you would have a pastel enchi
