==Shades== {{Main|Shades of chartreuse}}
==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.
==In nature== Yellow-green algae, also called xanthophytes, are a class of algae in the Heterokontophyta division. Most live in fresh water, but some are found in marine and soil habitats. They vary from single-celled flagellates to simple colonial and filamentous forms. Unlike other heterokonts, the plastids of yellow-green algae do not contain fucoxanthin, which is why they have a lighter color.
==In popular culture== <!--If possible, when adding to this list, please try to ascertain whether the color being referred to is the web color chartreuse (chartreuse green) or chartreuse yellow (traditional chartreuse) and indicate which one it is in your entry-->
