I'm Green and he's Yellow. What are we?

• "Green plus yellow equals yellow-green, otherwise known as chartreuse! This color is wild, electric, and is usually used in design, art, or fashion when the creator wants to be a bit shocking and stand out." History and Etymology
• The name Carthusian is derived from the Chartreuse Mountains in the French Prealps: Bruno of Cologne built his first hermitage in a valley of these mountains. These names were adapted to the English charterhouse, meaning a Carthusian monastery. These monks started producing Chartreuse liqueur in 1737. https://en.wikipedia.org/wiki/Chartreuse_(liqueur)
