I recently hatched out a pair of Savannahs (Cinnamon Mojaves)... Preshed I was pretty sure they were Pewter Savannahs and even got a couple responses here, but embarrasingly had to admit to a possible customer (after he said he didnt notice the Pastel), that they indeed looked more like Cinnamon Mojaves... I am guessing that a Black Pastel Mojave would look similar to this...
