All colors of coturnix originate from the wild pharaoh. So by saying the rosetta is a split, they all are splits. The roux spontaneously evolved from the wild pharaoh, but other than that, all colors were created from one. The codes from the link is nice, I like it, but people like simple so I tend to talk that way on the forum. It's nice having someone else interested in color though. If you need to chat, let me know. Lots of people are working together on standards. This is good! Coturnix deserves one too.
