I'm thinking of picking up a black pastel on trade. Havn't readly found much about them. how are the mixes of them? Blackpastel/spider? or /butter? or blackpastel/pastel? or /pinstripes? or anything else?? 
I've seen some that almost look normal and some that are defently realy dark.
Any sugestions??
