I was been looking at some mono fishing line and trying to think this through. the line is called Cajun Red and looks red. The theory is that the red line becomes invisible to the fish under water. I know from my experience as a scuba diver that as you go deeper you loose the ability to distinguish color and red is the first thing to go so I understand what they are saying in this respect.
That said we use a lot of red on saltwater flies and some times even use red hooks referred to as blood hooks to give the impression of a wounded bait fish.
So what is it with this Cajun Red?? Are they trying to sell folks a bill of goods or is the red on our flies wasted?
Just food for thought.
Thanks for the input,

“PC” is for Plant City not Politically Correct. if you wanna catch something ya gotta get a hook in the water
I vote for “bill of goods”
The color red, below a certain level, looks dark gray to black. It doesn’t disappear.
The color of blood looks the same to a fish, no matter if they expect to see red or just “dark”

Is it flourocarbon… To me it sounds like vanish transition flourocarbon… it is bright yellow out of water for the fisherman’s ease to see and tie nots… but loses all color under water.
ok heres your answer from the book “Fish” by Peter B. Moyle
Red coloration: In a world filled with predators, it seems strange at first so many fish are bright red or have red spots, stripes, or fins. "Red snapper is commonly sold in supermarkets; cardinal fishes and red squirrel fishes are among the most abundant fishes on coral reefs; the upstream migration of sockeye salmon, with their green heads and bright red bodies, is a frequently photographed spectacle. Although red is one of the most visable colors (to us) on land, it is frequnetly one of the least visible in water. Water is a selective filter of the colors of the spectrum, and red is filtered out in the first few meters. Red is also the first color to fade out at dusk and the last to appear at dawn. Thus most red fishes in the ocean live below the depths of red light penetration or are active only at night. Either way, they are difficult to see.
In shallow water, many fishes, such as sticklebacks and trout, use red as a breeding color. The fact that most such fishes confine the red to the males and develop it only during the breeding season is a good indication that it does make them more vulnerable to predators. This is balanced by the fact that bright color seems to make males more attractive to females. Red for such fishes represents a compromise between these conflicting demands of attracting females and avoiding predators because it is highly visable at close range or in bright light, but considerably less so at a distance (when viewed at an angle through water), or when the fish is under cover or in the shade… You were lucky that I was studying for class or you never would have known Rusty.
