Black Pastel Butter "Black Butter"?

[bimmer28]

I bought this guy from a reptile show, a smaller show from a considerably much smaller breeder. The snake came from a

Black Pastel het. Ghost x Butter het. Ghost

and was sold to me as a Black Butter. Ive been trying to find the black pastel in it and I am new so I am not the most experienced. to me he looks like a really nice butter. I have posted a collage of pics of him in my bathroom with about 225 watt CFL lighting and posted a pic of my lesser in the same lighting for comparison. Also have a flash picture there labeled. The bottom pic is 2 pictures of the lesser photoshopped together

thanks for the help. please help me point out what I may of missed that identified it as a black pastel.
