I would have to agree, there are dirty dark pastels and very nice yellow bright pastels, I wouldnt call them different morphs because they look different, they are both still pastels. . . When I first started there were already enough morphs for me to try and remember and figure out now for all those newbies out there it just gets more confusing, I always have numerous emails in the inbox asking the difference between this and that. I have seen Pieds come from Africa mixed into bags with normals now you don't see people calling them something new because they are a new line of pieds from Africa they are still pieds. If a morph is really something different like blue, green and purple then prove it out and call it rainbow ball but if it is a snake that looks like a morph that is already proven then contact the breeder who produced it ask questions send them pictures, then prove yours out and see what comes of it. . . .just my two cents
All in all great project, again I'm betting it's recessive and i'm sure the snake has a bright future breeding with you guys. . . best of luck!
