Eye color of gamefowl as bases for breeding

The breeding of gamefowl is very challenging since there are many things to consider when starting up breeding gamefowl. As far as I know the things to be considered when breeding gamefowl are the foundation bloodline should have a good quality. A winning bloodline and it is come from a well-known breeder. The brood cock should be pure not a battle cross, if it is a battle cross it should be a multiple winner in bigtime derby. The brood cock is high in station, good body formation and better bone structure. For the brood hen the characteristics should be high station, good body formation and both brood cock and brood hen should be in good health. One thing that I am confused is about the eye color of brood cock or brood hen to be chosen.

According to some breeder they prefer to choose the gamefowl that has red eye because it can see clearly then a gamefowl with dark eye especially during night. As we all know that all big time derbies are usually held during night time, so they prefer to breed the red eye gamefowl than the dark eyes.

There are also game fowl that has a light yellow eye, according to some breeder game fowl with light colored eye cannot see very well especially if there is a light example fluorescent light. During big time derby lights are always shinning in the cock pit.

My question is what eye color should be choose or should be considered when choosing a breeding material? I do some research and I found out that more game fowl breeder prefer to choose the game fowl with a red eye because a game fowl with a red eye can see very well during day time, night time and even if there is a light.
