It seems to me that the color of your cows is like marketing. The product is the same, the package is different. How does this effect your cows if at all. I've heard that white cows don't do as well here in Texas because of the sun and skin problems. I've also heard that black bulls tire out easily (not being able to service the cows) for the same reason. Darker colors absorbing heat. I don't know. I don't have any experience with this. School me.
