The yellow-green French liqueur made by Carthusian monks at the Grande Chartreuse monastery since 1737, from a recipe of 130 herbs known to only two living monks at any time. The color is the base spirit chartreuse jaune in a glass: a saturated, slightly green yellow that's brighter than lemon and warmer than lime. The liqueur gave the color its name, not the other way around.
