You will get 50% calicos and 50% super calicos, super calicos are mostly black with white strips and patches they look very nice. I have babies fom my calico girl x hrp and they are nice looking, i ended up with 50% calico blue and Pink blues.
I really hope so. I have seen the very dark calicos you mentioned. My pair is a little on the lighter side but I'd love there spawn to be at least like the parents.
