pueblan breeding questions!

[mild]

I have a few questions on breeding pueblan milk snakes.

First off this will be my first breeding project along with a pair of corns i plan to buy. I have one year exp with snakes but no exp with breeding.

Im going to be buying a 6tub rack system from boaphile and was going to house it with 1.1 corns and 2.2 pueblan milks. My first questions is would you recomend buying two of the same color phase for breeding or buying something like:

1 oreo
1 orange
1 apricot
1 albino

I would still want them as pets just as much for breeding so thats why i wanted to get different colors so each one would be different.

Any tips, breeding or carehseet pages would be nice.
