Pat,
I think maybe the "niteglo" color you're talking about is their standard glow overcoat that mimics the glow in the dark color we're used to seeing on Frisbees and other toys. I'm pretty sure they have that technology but I'm not sure it will be introduced with these first offerings. It may come to the party a little later with purple as a date, I don't know.
There is no doubt that these colors will help set a bait apart from everything else in murky water, under low light conditions, or at extreme depth. Along with the UV Blast they will be another tool in the bait making tool box.
