# Shades of green

Varieties of the color green may differ in hue, chroma (also called saturation or intensity) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below.

## Core definitions of green
### Green (RGB)

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 (HTML/CSS color) (Office Green)

The color defined as green in HTML/CSS color standard is the color called green, low green, or medium green in many of the older eight-bit computer palettes.
Another name for this color is green W3C or office green.

### 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 is a color space that specifies colors based on three color dimensions: hue, value (lightness), and chroma (colorfulness), spaced uniformly (in terms of human perception) in three dimensions in the Munsell color solid. In order for all the colors to be spaced uniformly, it was found necessary to use a color wheel with five, non-arbitrary, equally spaced primary colors: red, yellow, green, blue, and purple.
The color of the sample is the most chromatic (colorful) green in the sRGB gamut that falls in the hue of 5G (primary green) in the Munsell color space.

### Green (Pantone)

## 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, also called emerald green, is a tone of green that is particularly light and bright, with a faint bluish cast. The name derives from the typical appearance of the emerald gemstone. The first recorded use of emerald as a color name in English was in 1598.

However, it is revealed at the end of the story that everything in the city is normal colored, but the glasses everyone wears are emerald tinted.

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.
The normalized color coordinates for emerald are identical to the color Paris green, which is the name introduced in England during the 19th century to market the dye that resulted from using the toxic inorganic compound created in Germany.

## Other notable green colors
### Celadon

Celadon /ˈsɛlədɒn/ 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 tenth 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 (Fe$_2$O$_3$ → 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".

### Rifle green

The source of rifle green is the Pantone Textile Paper eXtended (TPX) color list, color No. 19-0419 TPX—Rifle green.
The first recorded use of rifle green as a color name in English was in 1858.
Rifle green is so named from the distinctive color of the uniform of rifle regiments (a form of light infantry) of a number of European armies, and is still used as such by rifle regiments in many Commonwealth armies, such as the Rifles and Royal Gurkha Rifles of the British Army and the Queen's Own Rifles of Canada.
Rifle green was originally adopted by rifle regiments in the 18th century, including the famous 95th Rifles of the Napoleonic Wars. As the traditional role of riflemen was that of marksmen and skirmishers who attacked behind the cover of trees, a dark green uniform was adopted as an early form of camouflage, as opposed to the colorful uniforms worn by other soldiers of the period. The vegetable based dyes used during the 18th and early 19th centuries were not fast, frequently fading after exposure to the elements to lighter shades of green or even brown. While this had advantages in terms of reduced visibility on active service, it did not make for a smart appearance on the peace-time parade ground. Accordingly, the color of the rifleman's uniform was progressively darkened until it approached black. After 1890 the development of chemical dyes permitted the adoption of the stable shade of rifle green now worn. In the U.S. armed forces, the green beret may be worn only by soldiers awarded the Special Forces Tab, signifying they have been qualified as special forces soldiers. The special forces beret is officially designated "beret, man's, wool, rifle green, army shade 297". Previously, rifle green uniforms had been issued to Hiram Berdan's elite 1st and 2nd United States Sharpshooters during the American Civil War.
Rifle green was the official uniform colour of the Canadian Forces (CF) after unification; it was thereafter generally referred to as "CF green". After the introduction of the distinctive environmental uniform (DEU), rifle green remained as the uniform colour of the winter land environment DEU; a short-lived tan uniform was worn in summer. After the demise of the tans, the rifle green DEU was worn year-round. Rifle green was also the colour of the uniform worn by the Northern Irish Royal Ulster Constabulary (RUC) until 2001 where the RUC was renamed the PSNI and while the uniform color remained the same, terminology changed to "bottle green".
Rifle green is 19–0419 TPX in the Pantone palette, or hex code #444C38 in the sRGB color space, as shown above. Despite being referred to as bottle green in some contexts, Pantone rifle green is a distinct shade from RAL 6007 Bottle green.

### Russian green
