How can a bull see red color if they are color blind?

That is the point; the bull cannot see the colour red at all, so it will not charge an object just because the object is red. A bull charges a waving flag because of its movement, as demonstrated and myth busted by Discovery Channel's Mythbusters: Tory was wearing an all-red jumpsuit and he stood perfectly still in a bullpen while a rangy rodeo bull was put in there with him (with a rodeo clown in the ring to keep Tory safe). The bull did not care that Tory was even present, nor even acknowledge his presence.

All the bull was concerned about was why he was here and trying to find some way to get out of the pen. Tory then wore other different colours besides red, like blue, yellow, etc. , and stood still in the bullpen while the bull was in there with him. The Mythbusters crew noticed the same behaviour by the bull.

Now when Tory or the rodeo clown suddenly made a movement, that got the bull's attention, and the bull came after that person or cape or whatever object that created the movement It should not be assumed that since a bull does not charge at the colour red but at the movement he is colour blind, because this in itself is not true. Cattle, like all other grazing animals, are only blind to the colour red, but they can see hues that range from yellowish green to bluish purple. Since bulls are cattle and cattle are prey animals, they tend respond to movement because they are designed to detect motion.

To a prey animal, vision is the most important sense, and because of this they are able to detect sudden movement sooner than a human can. Prey animals are sensitive to sudden movement as it is often a sign of approaching danger. Fighting bulls respond to the sudden movement of the cape because of this instinctual behaviour that has been enhanced through artificial selection to create a breed of cattle that are "great fighters" in the bull-fighting arena.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
