You are confusing me with this question, do you mean if you make a preset the colours will all be the same? Although I can understand a few parts of this:
Yes, you can use colours from the Feral Heart character creator, and possibly even more.
As for the markings, If I read it correctly, you want to know if you can use the markings in-game, yet have more than one on lets say body?
No, you cannot use th markings from the orginal Feral Heart game, you would have to attempt to copy them the best you can if you want those.
