Based on my research on this topic that’s not dicyanin. If such a dye exist that allows people to see their etheric body and visibily see the astral plane, its most likely going to have a lot of misinformation about it.
Spectauranine is dicyanine
"In the first edition of his book “The Human Atmosphere or Making the Aura Visible with the Aid of Chemical Screens” Walter Kilner wrote: “A few friends who have made a thorough study of this substance advised us to disclose the true name to the dye we were using. We also wished to do so, but now it is unfortunately too late, because the name “Spectauranine” has been scattered all over the book, and the book is already at the printers. The real name of this dye is dicyanine. The blue dye mentioned in the book is the dicyanine solution. The red dye, on the other hand, contains carmine. These four glasses, two dye stogs per glass, are only necessary, which are necessary for the observation of the aura.” However, dicyanin was already produced in the previous century by German companies, for example, by the company “Meister Lucius und Brünning“, which also produced dye sensitizers for photographic plates.

There’s multiple dyes the red one was one the Vietnamese conspiracy was based on.
