Well, I know that with fishing trout, with nightcrawlers specifically, I have outfished people next to me 3:1 using the owner (red) octopus hooks, compared to my neighbors normal bronze hooks. I believe in it and we were fishing 40 feet of water so it had to be the hook color. That's my feeling anyway. When spectrums are concerned they are relating information pertenent to humans, and fish dont really care about that

I think that's why red is such a great color in saltwater plastics. Think about Iron ,made specifically for white sea bass. All white with the red S. I have caught more fish on that, than people with all white jigs. Been there done that type of thing.
