COLOR-SENSE 93 



perceiving color in large masses can have but little use, 

 though in the latter the power of seeing green in large areas 

 might be of some assistance in their search for food. There 

 can be no doubt that bulls in bull-fights are excited into a 

 state of rage by the banderilleros flaunting red cloaks in 

 front of them. I would suggest that the perception of red, 

 presented in this way, excites in them the same instinctive 

 feelings and reactions as that produced by the sight of 

 flowing blood— the inevitable accompaniment of combats 

 in which the flesh is gored with horns. We ourselves use 

 the expression "seeing red" to describe the feelings which 

 excite us to uncontrollable vengeance.
