Marans genetics

Ok so two questions
I can not find any golden salmon nor columbian.
To start from scratch what would I need to cross to get this going on both colors.

I would suggest to keep looking there are salmons though the ones I had didn't have good egg color...I don't know who has columbians but to try and just make them isn't a good idea.......
