This here is an easy but effective one and looks nice on any style of bait I have tried so far (no swimbaits...yet).
Black colorant
.035 red flake to your liking
Orange/brown side
1/2 cup plastic
4 drops natural (Lurecraft)
2 drops Root beer (Lurecraft)
1-2 drops orange (Lurecraft) I say 1-2 simply for how much orange you want. I prefer one, my buddy wanted 2 for more orange.
Tip of a toothpick of white for some opacity, same can be achieved with salt if you prefer.
Laminate
Swirl
I know it looks like it isn't the same color but I assure you it is, that's just the effect the black has on this color; it doesn't quite retain the orangeness of it very well. I suppose if you truly wanted that orange and planned on doing the swirl you could just add even more orange to try and achieve that look
