Green is a color seen commonly in nature. Many plants are green mainly because of a complex chemical known as chlorophyll which is involved in photosynthesis.

Green light has a wavelength of roughly 520–570 nm and is one of the additive primary colors. It is the complement of magenta; more properly the color #FF00FF. People who are red-green color blind can often distinguish between the two colors but confuse them with other colors, for example, bright green with yellow; dark green with brown.

• Green also serves as a symbol of the Esperanto language. It is said that the color was first suggested by an Irishman, Richard Henry Geoghegan, who apparently suggested it as it was the color of his country and because it is the color of hope, hope being a strong theme in Esperanto culture. The color is particularly associated with the green star, and is seen too on the Esperanto flag.

"Green" as a political ideology

The 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. Those 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.

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 fanclub whose drivers used the color green to distinguish themselves from the opposing "Blue Party".

The flag of Libya is plain green (the traditional colour of Islam), the only current national flag of a single color.

Green is also the color of supporters of Taiwan independence in opposition to the unification-leaning pan-blue coalition. This symbolism comes from Taiwan's tropics and is unrelated to environmentalism or the Green Party.

Green as a symbol

Green is the color of the back of U.S. currency, and thus carries a strong connotation of money, wealth, and capitalism. This is especially true in the U.S., but the symbol of the dollar worldwide makes it a wider symbol. This is illustrated by a joke told in the days of the Soviet Union: "Name something green, other than money", with the correct answer being "A ruble".

In North American stock markets, green is used to denote a rise in stock prices. In East Asian stock markets, however, green is used to denote a drop in stock prices.
