I hoping someone could point me in the right direction for a formula for a respectable Tennesee shad color for a soft jerkbait.  I have tried now for sometime, but they all end up looking like mud to me.

The only Tenn shad color I am familiar with is from some crankbaits I own.

Pearl belly/ olive green/chartreuse sides with black on top. It would require a three-part pour. What would be easier is pouring a solid-pearl stick and use Spike-It or Colorite* for the sides and top. The dye is permanent and creates nice color combos.

This is a two-pour laminate:

Instead of pearl powder (very expensive), I use sugar flakes (very inexpensive).

*(Colorite can be ordered direct and is cheaper than from BPS.)

thats what I was trying to copy (closely match) was a crank bait color.  Although I have to admit, after seeing your bait, it looks REAL nice.

For my Tenn Shad jerkbaits. I pour a pearl belly with at MF Motor Oil back.
