Pair my horses!- 1 mil EVD!

So I totally suck at pairing horses for breeding. I don’t plan on breeding them until they are 12 years old, and only plan on breeding them each twice. But I would like to go ahead and get an idea of breeding pairs. I’m not worried about stats, but coloring and confirmation.  The paint that I have now are the beginning of my new line-  So they are all store-bought.

Whoever can pair them up and explain to me why you chose that particular pair, I will give you 1 million EVD!
