The color displayed at right, electric green is the brightest possible green that can be reproduced on a computer screen. This color is a close approximation of spectrum green, one of the three primary colors of light, along with red and blue.

Green takes up a large portion of the CIE chromaticity diagram because it is in the central area of human color perception.

When approximated (with less brightness) in pigments, this color is called bright green.

Kelly green, also known as grass green or pigment green, is achieved by mixing cyan and yellow in equal proportions. This is the color green that is shown in the diagram located at the bottom of the following website offering tintbooks for CMYK printing: .

This color is also called grass green. Colored pencils of the 1950s colored this were sometimes called grass green. Psychedelic art made people used to brighter colors of green, and pigment colors or colored pencils called "bright green" or "true green" are produced which approximate (with much less brightness that is possible on a computer screen) the electric green shown above.

The conservative shade of green shown at right, office green, was the original color designated as "green" for computer displays in the 1980s.

It was apparently chosen because it is the color of the green-colored pencils used by accountants and the color of green office file cabinets.

Green in nature

Green is common in nature, especially in plants. Many plants are green mainly because of a complex chemical known as chlorophyll which is involved in photosynthesis.

Some animals are green: these include some frogs, toads, some turtles some lizards and amphibians, some snakes, some birds such as parrots, caterpillars and some insects such as praying mantises.

Colloquial expressions

• Jealousy is also called the green-eyed monster (after a phrase in Shakespeare's Othello).
• Closely related, a person can be said to be "green with envy". Substances that may impart a greenish hue to one's skin include biliverdin, the green pigment in bile, and ceruloplasmin, a protein that carries copper ions in chelation.

Politics

The environmental lobby or ecology movement uses green because of its common occurrence in nature. Greenpeace, an ecological group, uses green because of its association with life and verdancy. Europeans who carry this into the political realm are called Greens:

There are political parties known as "Green Parties" in over one hundred countries throughout the world (beginning primarily in Europe, though similar parties have taken root around the world). The more generic term "green party" is used for parties that emphasize environmentalism, but it is increasingly out of favour as the Global Greens have succeeded in uniting almost all such parties under a Global Green Charter. In the UK the ecology party became the Green Party. In the United States, especially in the state of Minnesota, green has been used by many Democratic candidates (blue, white, gold and green colors show up frequently in official state imagery in Minnesota), though it does not necessarily symbolize adherence to Green principles. Minnesota Democratic-Farmer-Labor Party Politicians to use green symbolically include U.S. Senator Amy Klobuchar, U.S. Representative Keith Ellison and late U.S. Senator Paul Wellstone. Wellstone was frequently and famously sympathetic to green causes.

A "Green Party" (or Faction) also existed in the Byzantine Empire for a while, but of course it had nothing to do with modern Greens. Rather, it developed out of a kind of chariot racing fan club whose drivers used the color green to distinguish themselves from the opposing "Blue Party".

Bartholomew I of Constantinople is often referred to as "the Green Patriarch" because of the support he has caused the Ecumenical Patriarchate to place for maintenance and protection of the environment.

The flag of Libya is plain green (the traditional color of Islam), the only current national flag of a single color. The flag of Hamas is also green, symbolising their Islamist ideological path.
