Well a good test is you go to your store and put some ink on a sheet of paper.
You then try to convince the lady (it usually is a woman) at the casher to let you use her black light detector for conterfeited money -> you will know instantly whiwh marker reacts the most
Unfortunately you will also notice that the brighter ones are yellows, greens and some orange/pink ones.
The blue ones are almost non reactive
