Chartreuse (US: /ʃɑːrˈtrz, -ˈtrs/ (About this soundlisten), UK: /-ˈtrɜːz/,[2] French: [ʃaʁtʁøz]),[3] also known as yellow-green, is a color between yellow and green.[4] It was named because of its resemblance to the green color of one of the French liqueurs called green chartreuse, introduced in 1764. Similarly, chartreuse yellow is a yellow color mixed with a small amount of green that was named because of its resemblance to the color of one of the French liqueurs called yellow chartreuse, introduced in 1838.[5]

Shades of chartreuse[edit]


The French word chartreuse means "charterhouse". The monasteries that the monks of the Carthusian order (who started producing Chartreuse liqueur in 1764) live in, of which the first one was established in 1082 by Saint Bruno, are called charter houses because they were chartered—and given generous material support—by the Duke of Burgundy known as Philip the Bold when he took over the area in 1378. Philip the Bold's elaborately decorated tomb was initially installed at a Carthusian charterhouse when he died in 1404.[6]

Chartreuse in nature[edit]

Yellow-green algae, also called Xanthophytes, are a class of algae in the Heterokontophyta division. Most live in freshwater, 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[edit]

Traffic safety[edit]

Chartreuse yellow is used on traffic safety vests to provide increased visibility for employees working near traffic. The chartreuse yellow background material, together with a retro-reflective satisfy the ANSI 107-2010 standard since 1999. High-visibility clothing ANSI Standards were adopted as an Occupational Safety and Health Act (United States) requirement in 2008.[7][full citation needed]

Film and television[edit]

The 1960 Universal film Chartroose Caboose featured a "bright green" colored train car.[8]

In an episode of Hogan's Heroes, the prisoners at Luftstalag Thirteen are given the task of painting the camp buildings chartreuse.


ACT Fire and Rescue tankers in chartreuse green

Since about 1973, a sort of fluorescent chartreuse green has been adopted as the color of fire engines in parts of the United States and elsewhere. The use of chartreuse fire engines began when New York ophthalmologist Stephen Solomon produced research claiming that sparkling bright lime-green paint would boost the night time visibility of emergency vehicles compared to those painted the traditional fire engine red.[9][10] The reason for this is the Purkinje effect, i.e., the cones do not function as efficiently in dim light, so red objects appear to be black. In Australia and New Zealand this form of chartreuse yellow is also known as "ACT yellow" as this is the color of the fire engines in the Australian Capital Territory.


When Bharatpur State was a princely state, it was the only political entity ever to have a chartreuse yellow-colored flag.[11]
