...the thing looked almost florescence orange... probably because it is 
actualy fluorescent orange when lighted with blue to violet and UV light.
Blue light is actualy energitic enough to cause fluorescence in several 
pigments.

That high visibility green probably absorbs a fair amount of blue. The 
blue probably is not energitic enough to cause green fluorescence, but 
enough to cause the orange one.
