First I will say where are you located?
In the US we have 49 different breeds of rabbits. Yes domestic rabbits all have the same genetics but if you are responsibly breeding you are not just crossing breeds for no reason. In the US there are many rabbits in shelters and we as Breeders do not want to contribute to this overpopulation. Hence Breeders choose a specific breed and then use the standard of that breed to try to attain a better quality animal.
Now outside of the US there was a girl, I do not remember where she was from but they did not have a rabbit population problem, she could find proper and long term homes for her offspring and her goal was to learn about rabbit color genetics. She imported different colors of rabbits and used them to figure out and do work with the color genetics. She was actually working on a Rufus project which interested me. If you are trying to do something like this you need to start with websites dedicated to color genetics in rabbits. There are not a lot of people on here that are well versed with color genetics (me included) so I don't know if this would be the right place for you to ask questions about them. Now when you start breeding you can ask questions because we have lots of people knowledgeable about breeding and baby bunnies.
If you are from the US or even the UK I will ask that you actually make a plan for a breeding program before you start breeding this one to that one. To be a humane breeder you need to find how you will sell or cull your offspring and which babies you will retain for the program. You also need to realize that breeding rabbits can be very difficult. You need to be prepared to have baby rabbits die and even mothers dying from birthing complications. You also need to check what common diseases you should be aware of in your area. Once you figure this all out then you can look into breeding for color genetics. You also need to try and find rabbits from reputable sources. Don't just go out to a pet store and start breeding those rabbits because they will probably come up with all kinds of recessive health problems like malocclusion, sore hocks, cryptorchidism, etc. you need to also figure out a documenting system to keep track of your pairings.
