It works with way with all the complex mutations from blue eye lucy, black eye Lucy, black pastel complex and YB complex.

So to make a pastel super stipe you need to cross Spector and yb together in the same pairing, with either of which having pastel as well. Hopefully this makes sense.
Is there someplace that has all the genes mentioned to date and what they are/are not allelic to each other? Or are the pairs you you mentioned the only ones who have these traits?
