When picking a stallion to breed to. Here's the controversial question I hear so much. Does color matter. To me I personally look for stats bloodlines temperament etc. but I've also known people who are like eww no it's a sorrel ewww it's a bay. 

No, color does not matter to me.  But, color sells. 

color only matters to people that don't have enough money to buy a good one 

It would matter to me on my mare that carries a dilute gene.  I would be sure to choose a stallion that did not also carry the dilute.  That is just my personal preference as far as possible offspring.
