Chartreuse is named after the liquour which is named after the monastary which is named after the mountains which is named after the village which is of ambiguous origin but likely named from a Gaulish tribe. So you're gonna have to rewrite an awful lot of history if you want to come after chartreuse.
I, for one, am willing to make this sacrifice. Specifically to say it's worth it for someone to rewrite a lot of history; I've got a thing going on so I can't volunteer for that even though I really want to darn.
It's named after the liquour, if you follow the chain of naming it goes beyond the mountains regardless but the color is named after the color of the liquour, not the colour of the mountains.
