Chartreuse

Chartreuse is a color between yellow and green.

It was named after a French liqueur that has a similar hue.

Chartreuse can be either a bright greenish-yellow or a pale yellowish-green, depending on the shade.

It is a vivid and cheerful color that can create a lively and energetic mood.

Some examples of chartreuse in nature are yellow-green algae, lime fruits, and some leaves and flowers.

Chartreuse is also used for traffic safety vests, fire engines, and some liqueurs.

• Chartreuse liqueur: This is the original source of the color name, and it is a herbal alcoholic drink made by Carthusian monks since the 17th century.
  There are two types of chartreuse liqueur: green and yellow.
  The green one has a higher alcohol content and a more herbal flavor, while the yellow one is sweeter and milder.

• Yellow-green algae: These are a class of algae that have a chartreuse color due to the absence of a pigment called fucoxanthin.
  They live in fresh water, marine, and soil habitats, and vary from single-celled flagellates to simple colonial and filamentous forms.

• Traffic safety vests: Chartreuse is used on traffic safety vests to provide increased visibility for workers near traffic.
  It is the color most visible to the human eye, and it meets the ANSI 107-2010 standard for high-visibility clothing.

• Fire engines: Some fire engines in the United States and other countries are painted in a fluorescent chartreuse green color to enhance their night-time visibility and contrast with the red of other emergency vehicles.
  This color was adopted after a research by a New York ophthalmologist in the 1970s.

• Fashion and design: Chartreuse is a bold and vibrant color that can be used to create striking contrasts and accents in fashion and design.
  It was especially popular in the 1920s, as it symbolized rebellion and innovation.
  More recently, it was worn by Michelle Obama in a memorable outfit, and it was declared the official color of 2020 by Etsy.
