How fishes see the color?

Not knowing the principal of how it determines which colors to use

It recommends colors entirely based on the theory that the most visible
color is the most likely to be eaten by a bass. That theory itself is
highly suspect, in that the vast majority of the things a bass is
conditioned to recognize as food in its natural environment are pretty
well camoflauged and don't qualify as high viz.

But the ONLY thing it measures is light intensity. It simply ignores
light temperature, contrast with existing background, water COLOR (as
opposed to clarity) and all of the other myriad factors that can alter
the outcome.

IMHO, even if it was accurate (which the original wasn't), and even if
it could find the actual highest visibility lure color (which it can't,
as long as it doesn't take additional factors other than candlepower
into effect) the theory that the color that can be seen best is most
likely to be eaten is still highly suspect.

I didn't have any idea, thanks.
how far from the bait this transiction is put?

The leader goes between the main fishing line and the lure. The
leader is always heavier test than the line. For example I use 40lb.
test leader on a pole with 17lb. test (Stren). The length of the
leader is a funtion of the pole length and the weight of the lure.
When I use a 2 ~ 2.25oz. spoon (Krocodile or Gator) on a 12' surf rod
I make the leader approx. 30 ~ 36 inches. I'll use a barrel swivel
to tie between the leader and the main line (17lb. Stren) and a snap
on the leader to connect to the lure. The leader has to loop knots,
one on each end where one is slightly larger than the other. The
smaller loop goes to the barrel swivel and the larger loop goes to a
snap. The main line (17lb. Stren) connects to the barrel swivel via
a palomar knot.

interesting.
in Italy and in all surf casting fishing and in Long Casting tournaments
we use also a strong line (about 0.60/0.80mm diameter) and we call
"shock leader" to connect the main line (0.20/0.35mm diameter) to the
rig set with big leads (3/6oz), you can see a sample here
http://www.pescainmare.com/newfoto/paternoster.JPG

but our shock leader is about 1,5 times the lenght of the road (usually
13') and the purpose is to receive the sudden and violent traction of a
ground or pendulum cast.
so, that I can't understand of your leader use is the purpose, being so
short.

Apart from absorbing the "shock" whether it be from a cast or a hard hit by
a fish, there are some fish that have sharp enough
teeth that fishing without a leader almost always results in your line being
cut. In sal****er, Bluefish come to mind as requiring
a short wire leader. Sharks require a rather lengthy wire leader, in which
they often roll. In England, those who fish for Pike
I believe use a short wire leader when bait fishing. Even a non-wire
heavier-than your line monofilament leader will provide
protection.

and also, some fish could cut the line with the dorsal fin. now I
undestand

there is the same fish in Italy, we call 'serra' and we fish it with
live mullets
