Which two colors of horse would you want to breed if you wanted to produce the maximum numbers of palominos in the shortest amount of time?

To produce the maximum number of palominos, you would want to breed a chestnut horse with a cremello horse. The cremello horse carries two cream genes, which dilute the chestnut's red coat to produce palomino offspring. This combination increases the likelihood of producing palominos, as each foal would have a 50% chance of being palomino if they inherit one cream gene from the cremello and none from the chestnut.
