AFAIR the original works about Harmalas, the yellow color is actually due to water inclusion into the structure (hydrate), and that pure dry HCl salt would be white/transparent. AFAIR it can be got by using strong HCl acid. But would again have to look up, if I still remember this correctly...
This would basically mean, one would have to consider also the water weight, when converting.
This makes sense. Harmala hydrochlorides are fluorescent only if dissolved - maybe the water complex interacts with UV light, giving it that nice golden glow.

Well I have recently converted harmine freebase to HCl salt by simply dissolving in HCl(aq) and evaporating the water, cycling the evaporating dish between oven and fan.
I wanted to drive the water and excess HCl out quickly so I used higher temperature (120 °C) - to my surprise, the harmala crystals got darker brown on top like if burned.
Maybe this is the anhydrous form or maybe I really burned it... I don't know.
