Hello Alexandros, you are absolutely right, Orgeat and Yellow Chartreuse have nearly nothing in common. I was simply intrigued by the pink line idea and wanted to try that without shopping for Orgeat (or making it myself). The way I understand this cocktail though, at least in the recipe, the Orgeat serves as a mellow sweetener that adds body to the drink.
In all its herbal complexity Yellow Chartreuse especially the Meilleurs ouvriers de France edition is a relatively mellow herbal liqueur with good body. In that sense even a Mastika, that I also love sparingly as a cocktail sweetener might have worked.
I‘ll have to give it a try with real Orgeat sometime soon.

Since I did not have orgeat on hand I replaced it with yellow chartreuse M.O.F.
Also very lovely.
