Magenta is not lit.

Have the magenta version bought it, we wanted to really touched a powder or a liquid put as a pendant in a mini-bottle.
All attempts have failed so far but, neither as a powder or with water or oil, the stuff lights visible.

In the big bag you notice after a very strong direct irradiation at least briefly an afterglow when it is absolutely dark. We suspect that really only takes up the outermost layer of energy and you will therefore not bring to light what is afterwards mixed. Say, applied colors might work. Helps us not stop.
