This might already be known but I learned recently that some of the Blaze PD colors are very UV (black light) reactive.
*Blaze Purple has no UV reactive qualities from what I can tell*
Blaze Blue, Green, Yellow, Pink and Orange all have a nice glow when put under a UV light at night. This is also what probably attributes to their brightness during the day in the sunlight (UV).
I have not been able to get a good picture of the green glowing but here is what I have done so far:
