Help please! coturnix tuxedo color mutation?

[calcifer]

Hi I am getting ready to buy my first hatching eggs and am wandering how true to color mutations breed? I have spent a lot of time looking at different breeders and it seem to me that different breeder flocks have slight variations even when they are supposedly the same color mutation, Is there really a difference or is it just the camera? Also how true to color do tuxedo hatch? I have found a breeder that seems to have a beautiful redish Tibetan tuxedo flock and am wandering if they are worth paying almost double the cost of other breeders? Lastly I am going to buy james marie silver collection when the price drops in a few months and when we talked he said to breed them with brown and white will A and M or the wild color mutation work?
