Green

From Free net encyclopedia

Template:Infobox colorGreen is any of a number of similar colors. Green is seen commonly in nature, like in plants. 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 considered 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.

The term "green" does not define an exact color unless it is conjunction with some standard like X11 colors or an absolute color space like sRGB.

"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 color 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 symbolizing earth, nature, and in a broader sense, life. It is also the color of the back of U.S. currency (giving rise to the slang term "greenback"), and thus carries a 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.

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.
