I was at a fishing seminar and the subject of red hooks & line came up. The question was how does the fishing industry advertise the use of red to not only help catch bass(say red trebles) but also be invisible to bass(say red fluro line)? On one hand they'll promote that a red treble hook will help attract bass but then say you would  use red fluro line because bass can't see it. I remember reading a post on this website a few years ago explaining how both can be true. Anyone remember or know this info?

catches fishermen not fish

red hooks reflect light so you get a red flash in shallow water.down deep they turn black so they are useless on deep cranks.red line is translucent so light passes through it.red is the first color of light to go away.the line then becomes greyish.being that most water is not gin clear the grey line disappears into the water.i caught the most fish ever in a season on red cast line.i am in my second season with flouro to see if i do any better.

I'm not totally convinced about the hype . What good would red line do in crystal clear water , it sure isn't invisible. It just starts changing to a grey color in about eight ft. of water.

The red hook hype I can see where that might work. JMO

While I can't back it up with scientific facts but if you want to catch bass on Toledo Bend your bait better have red in it and that is a fact.

I do use red line, but haven't really noticed to much of a difference, so i'm going to just say prefference.

I've never tried the red line.All the water I fish is stained most of the time.I have used red hooks and can not really tell if I caught anymore thana regular hook.

  What I can tell you from my limited experience is that I catch more fish on a watermelonseed or green pumpkin worm etc. with red fleck than I do without the red fleck.Why?Beats me. :-/

Light goes through red line, its transparant

Light reflects off of red hooks, so the bass can see the red of the hooks until certain depths.

I have tried red line and I haven't noticed any difference between it and other lines I've used. I personally don't like it. On the other hand, I do put red hooks on most of my shallow cranks, topwaters, and plastics. Last summer I did an experiment with wacky rigged senkos with red hooks and with black hooks. The senko with red hooks caught about 25% more fish than the senko with black hooks. That said, I was a little more confident with the red hook and that may have effected my results

and grey becomes very hard to see in water.even in clear water grey will not stand out when you have other objects in the water.like i've said before,you have to study underwater photography to get it.

Dodgeguy is correct. There was a really good article in In-Fisherman on this a month or so ago. They had fisheries "scientists" even and their conclusions were essentially the same as what dodgeguy has stated above.
