New hairscolors and cc?

I'm only guessing,.. I think most cc hair will work but I am expecting a few occasions related to DNA where the cc hair can't perform the color that the game suggests. In those cases I have no ide if the game will then know that it should rather relate to the old color system, which most cc creators were loyal to. It might be an minor issue though, as the game already randomly selects the color next to the parent's color, causing a bit more variety than if kids could only inherit the exact same color. I don't know the exact algorithm for the DNA though, guess nobody does. In a worst case I hope it's not more fuss than we can adjust in CAS as the kid grows up.

Eager to learn more about this as my game depends on CC hair.
