there is a place to click on to download a pdf of Bob Carr's color charts. That might help you. Bob Carr was a physician and very detailed about his hybridizing.
I, myself, did not notice a tendency one way or the other for which traits come from which parent. You can have hundred seeds from a cross and have all of them look different, or have all look so much alike you can't tell the difference.
So, someone with more years than I have will have to answer.
I always tried to put two parents together that complimented each other's faults. If one had a beautiful face, but no branching, I made sure the pollen I used with it was all from plants with great habit.
I have a friend who insisted on crossing reds and yellows and purples and yellows. After a couple years of seeing seedling beds full of brown and muddy colors, he has stopped that.
One general rule I heard is that you can cross a melon or a polychrome to any color.
Now I will defer to others who have more experience than I do.
