Green 

The color defined as green in the RGB color model is the brightest green that can be reproduced on a computer screen, and is the color named green in X11. It is one of the three primary colors used in the RGB color space along with red and blue. The three additive primaries in the RGB color system are the three colors of light chosen such as to provide the maximum range of colors that are capable of being represented on a computer or television set.

This color is also called regular green. It is at precisely 120 degrees on the HSV color wheel, also known as the RGB color wheel (Image of RGB color wheel). Its complementary color is magenta.

HTML/CSS uses the name lime for this color, using green to refer to a darker shade. See the chart Color names that clash between X11 and HTML/CSS in the X11 color names article to see those colors which are different in HTML and X11.

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

Green (CMYK) (pigment green) 

The color defined as green in the CMYK color system used in printing, also known as pigment green, is the tone of green that is achieved by mixing process (printer's) cyan and process (printer's) yellow in equal proportions.

The purpose of the CMYK color system is to provide the maximum possible gamut of color reproducible in printing.

The color indicated is only approximate as the colors of printing inks may vary.

The color displayed is an approximation of the CMYK color on an RGB screen, and cannot replicate the color accurately.

Green (NCS) (psychological primary green) 

The color defined as green in the NCS or Natural Color System is NCS 2060-G. The natural color system is a color system based on the four unique hues or psychological primary colors red, yellow, green, and blue. The NCS is based on the opponent process theory of vision.
The Natural Color System is widely used in Scandinavia.

Green (Munsell) 

The Munsell color system (Munsell 5G) includes a color defined as green. The Munsell color system is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (color purity), spaced uniformly in three dimensions in the elongated oval at an angle shaped Munsell color solid according to the logarithmic scale which governs human perception. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five primary colors—red, yellow, green, blue, and purple. The Munsell colors displayed are only approximate as they have been adjusted to fit into the sRGB gamut.

Green in biological 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. Many shades of green have been named after plants or are related to plants. Due to varying ratios of chlorophylls (and different amounts as well as other plant pigments being present), the plant kingdom exhibits many shades of green in both hue (true color) and value (lightness/darkness). The chlorophylls in living plants have distinctive green colors, while dried or cooked portions of plants are different shades of green due to the chlorophyll molecules losing their inner magnesium ion.

Emerald was invented in Germany in 1814. By taking acetic acid, mixing and boiling it with vinegar, and then by adding some arsenic, a bright blue-green hue was formed. During the 19th century, the arsenic-containing dye Paris green was marketed as emerald green. It was notorious for causing deaths due to it being a popular color used for wallpaper. Victorian women used this bright color for dresses, and florists used it on fake flowers.

Other notable green colors

Celadon 

Celadon  is a pale greyish shade of green, or rather a range of such shades. Celadon originates as a term for a class of Chinese ceramics, copied by Korea and Japan. However, the name, which is European, may originate from the character Celadon in L'Astrée, a French pastoral novel of 1627, who wore a light green color.

Celadon glazes were very common, with the green color being reliably produced from about the 10th century onwards; this was appreciated in Asia for resembling jade, the most prestigious material of all. The glaze color comes from iron oxide's transformation from ferric to ferrous iron (Fe2O3 → FeO) during the firing process, but is affected by a wide range of other factors and chemicals, making the precise color very difficult to control. As well as green, a wide range of browns, yellows, greys and sometimes blues all count as "celadon".
