Chartreuse (US: /ʃɑːrˈtruːz, -ˈtruːs/ ⓘ, UK: /-ˈtrɜːz/, French: [ʃaʁtʁøz]) is a French herbal liqueur that has been made by Carthusian monks since 1737, reportedly according to instructions set out in a manuscript given to them by François Annibal d’Estrées in 1605.[1] It was named after the monks’ Grande Chartreuse monastery, located in the Chartreuse Mountains north of Grenoble, France. Today the liqueur is produced in their distillery in nearby Aiguenoire. It is composed of distilled alcohol aged with 130 herbs, plants and flowers, and sweetened, though the exact recipe is known only to select monks. The color chartreuse takes its name from the drink.
How is you colleagues able to taste color?
Synesthesia.
As with another well-known French hard liquor, drink enough and you, too, just might taste colors swirling on your tongue and hear emotions swirling in the sky.

~Absinthe does not actually cause hallucinations~
Thought it depended on what kind you get. The one generally available in North America is just strong liquor like bacardi 150 (though more of a zambooka flavour), but actual absinthe is made from some tree wood that is hallucigenic. At least, that’s how I understood it; I’ve only tried the boring kind.
Wormwood. Pretty much banned everywhere now though.
It tastes like the essence of green. I love it.
