It is my understanding is that it has to do with light reflection, the
hook/crankbait reflects the light (red color), the line does not reflect the
light, thus becomes hard to see.

While I was in the reading room perusing the latest issue of BassMaster,
and having read every article 2 or 3 times, I noticed the Shakespeare ad
for Cajun Red line. The ad states the advantage with this line is its
invisibility, particularly after 3 feet of depth where the fish cannot see
the line. This is due to the water filtering out red on the lower end of
the light spectrum, rendering the line more or less invisible to fish.
OK, this makes sense to me, sort of.

I must have half a dozen crankbaits of various sizes in red, most of which
run a depths greater than 3 feet. I have caught good numbers of fish on
these red cranks. Now, how in the hell is this possible if the bait is
mostly or entirely invisible to the fish? I must be missing something in
this equation.
