The components of Nightmare are Basic Black 5300 and Velvet Midnight 2163. So Basic Black is in there already.
I am guessing you don’t have a snippet of Black Raspberry that you can post here? I searched online and found only Black Raspberry Jam by GAST. Is that the same color?
I have a bunch of GAST at home, let me dig it out once I go home from work.
