Seems there was a treasure ship on its way back to port. About  
halfway there, it was approached by a pirate, skull and crossbones waving  
in the breeze!
 
“Captain, captain, what do we do?” asked the first mate.
 
“First mate,” said the captain, “go to my cabin, open my sea  
chest, and bring me my red shirt.” The first mate did so.
 
Wearing his bright red shirt, the captain exhorted his crew to  
fight. So inspiring was he, in fact, that the pirate ship was repelled  
without casualties.
 
A few days later, the ship was again approached, this time by two  
pirate sloops!
 
“Captain, captain, what should we do?”
 
“First mate, bring me my red shirt!”
 
The crew, emboldened by their fearless captain, fought heroically, and  
managed to defeat both boarding parties, though they took many  
casualties. That night, the survivors had a great celebration. The  
first mate asked the captain the secret of his bright red shirt.
 
“It’s simple, first mate. If I am wounded, the blood does not  
show, and the crew continues to fight without fear.”
 
A week passed, and they were nearing their home port, when  
suddenly the lookout cried that ten ships of the enemy’s armada were  
approaching!
 
“Captain, captain, we’re in terrible trouble, what do we do?”  
The first mate looked expectantly at the miracle worker.
 
Pale with fear, the captain commanded, “First mate…. bring me my  
brown pants!”

and it’s red, for the same reason most of their outfits are a shade of red of some sort too…
 
It hides blood stains :P

Yeah, they’re colorblind. They react to the movement of the matador flapping the cape around.

(Not a Joke)I think the actual fact is bulls are color-blind.  
(Joke) Last time they hire guest judges.
