No. In this fashion of creating a core color, we filled one side of a mold by hand with plastic, then added a drop of raw colorant [midnight blue in this one] to the head end of the hand pour using a toothpick. The mold gets closed and clamped and then the rest of the mold got filled by injection. As the injected plastic runs into the mold it washes the core color along with it. If you look closely at the top and bottom baits in the picture you cannot see the core color at all viewed straight on from the side. When viewed from the bottom, as in the two center baits, you can see how the injected plastic has pulled the raw color along with it thru the mold.
This makes a "flat" core color in the bait's body and is most visible from the top and/or the bottom. There doesn't appear to be anything there if viewed straight on from the side but if you begin to turn the bait ever so slightly the color colors immediately becomes noticeable. The tail plastic is thin enough that the core color is readily seen and being random as the color gets washed along it creates some very cool marbling. You won't find the tail splash like you see here doing the sprue pour and injection but you will get a more two dimensional core.
