Here.....these are what I was using last fall. I had to dig the bag out of the pail in the boat and then give them a bath of sorts to make them look good enough to show ....

If my memory is right they are nothing more than a silver pearl belly and my version of bluegill, clear with blue, green, copper and purple glitters. AND a good shot of uv in each color plus in the cover dip. The one on the lower right corner that's belly up is the one I had on the line...the hook scar is in it.
There are periods of time when I believe in having either a very, very transparent bait or one that is absolute black as a reverse contrast color is the best way to fish color-wise. Just before or right at first light I like to go very clear. At last light or just after I prefer black. I have both in the bucket but the black in sunlight doesn't show me the uv on it like these will even though I did top coat them with enhanced clear. If you look closely at the "skin" on these you'll see the faint bluish hue they have.
The very small ice baits I make for a local couple bait shops have uv enhancer in each color of plastic. Its hard to keep them in stock. I think its the enhancer.
