I do focus on the species of crayfish, in a system, and
what phase they are in(soft shell, new shell, ready to
molt old shell, etc). For the native nothern crayfish,
something in green pumpkin, with Blue Flake, is good for
all phases except soft shell. In shoft shell, Yamamoto’s
brown smoke is killer. If the system is infested with
exotic Rusty Crayfish, watermelon/red flake, or green
pumpkin red flake, or green pumpkin, accented with a orange
Spike-it pen, usually gets me through all of their phases.
If the Rusty’s are really faded, sometimes a blonde pumpkin,
with copper flake clearly gets attacked more than my typical
offerings.
I am not sure what Black/Blue flake is suppose to look
like, but it doesn’t match anything I find in northern
Wisconsin Lakes. I don’t fish that color combination very
often, because I don’t find it as effective as other
colors mentioned. But that might also be because a
bunch of bass guys fish it
Now on the river,
there I do fish it, but I believe it is a better contrast,
in dirty water. Kind of in the same set with June Bug,
and Black Neon(black red flake).

P.S. I emphatically agree with Blue on the flake color
being important.
