So this morning Nordy sends me a pm asking a couple questions. The discussion runs from one topic to another and then we hit on the Ring-It mold and some possibilities that it holds. I suggested that perhaps the bait shot with a glow tail would be a good combo in a walleye bait since there is no such animal on any market right now. After yacking with Nordy I started thinking along a different line, this one using glow as a core color.
Here is the finished bait with a glow core. The chartreuse is as transparent as transparent can get yet the glow color inside is virtually invisible.

The core color was made using a small amount of stabilizer mixed with just enough of Do-It's yellow glow pigment to create a loose glow fluid similar to colorants. I did a spoon pour in the un-vented side of the mold for a core base, then dotted the glow core on in three places along the length of the hand pour, closed the mold and finished with the same chartreuse. I haven't got a super suitable area inside to shoot glow colors but the photo shown here certainly does show up along the core color. In the hand the glow core is much more defined than in the picture since the camera can't filter the glow running outward away from the glow core and I am probably shaking like a Pekinese crapping a peach pit trying to hold the camera steady....too lazy for the tripod.

For the glow picture, the plastics were laid out in shaded sun for as long as it took to get the top picture, then one was taken indoors to relative darkness for the glow pic. As mentioned, in the hand the glow doesn't seem to wash thru the whole of the plastic and the line is way more defined.
Kind of putsy work but still another option for the venturesome.
