Glow is the same on all of them. They do glow a long time when properly charged. I had a couple of them under a 365 nm LED blacklight for about 5 minutes, and they're still glowing 3 hours later.
I actually made 5 of each. Some individual heads glow more than others, depending on how much glow pigment landed on it. Kind of like on metal flake colors how some heads end up with more glitter than others, or more glitter on one side.
Since it didn't change the color of the base coat on the watermelon flake and chart green, you could fish them as normal colored heads during the day and glow heads after dark. The unpainted heads were fairly new, so they hadn't oxidized much. They have a silvery-green sheen to them.
I'm interested in trying the same trick over other like colors such as blue, pink and orange. I think Chuck and Deb have the cheapest prices on the super glow paints.
