frozenfire said:red is only visible to a certain depth, after that, they blend in with the rest of the environment and turn darkish/blueish.
this was first noted in marine fish. many people wondered why they ahve these gorgeous colours that are so pleasant on the eyes and so attractive. wouldn't they ultimately get the attention of predators? they did the studies and showed that bright colours like red disappear in deeper waters!
also, bleeding fish is a complete joke to me as well. as we've all noticed, in water, if there is a bleeding fish, you will only notice it if the fish still, and there is no current. you can see how fast the blood diffuses into the water and disappears. especially on smaller fish (lure sized) you never even really see the blood in teh water, it just gets into the water and disperses quickly. In my experience, only pike seem to have blood that clots quickly and is visisble in the water.
I guess this is the idea behind red color mono and braided line for deeper water applications the red color blends in with the environment quickly at the higher depths.... I guess we will see this season I have one reel spooled with the red power pro....
