Just noticed (by accident really) that some goose biots glow when the UV light is shone on them, especially the fluorescent ones? However, I tried some orange ones and they glowed bright lime green?!?! Is this something to do with the dye / dying process? Any information would be interesting and appreciated. Thanks

Just the dyes that are used. Often you find titanium dioxide in the dyes which shows up under black light. Chartreuse always reacts.
