In muskie fishing the sky is the limit, basic colors could be black, black / silver, high contrast is big in off colored water. through in some fluorescent orang, or fluo. red, I like fluo. red best in realy stained water with flat black dots or stripes for contrast. clear water, mostly natural
type patterns with some room to play with color. throw in some red as a
"wound".
I have some in hot pink/fluo. org/electric blue, so anything is possible.
Did your customer give you any peramiters?
