Blue has been an important colour throughout history, as lapis lazuli in jewellery and as a pigment, as cobalt blue in colouring porcelain, as woad and later indigo dyed clothing all the way to the modern synthetic pigments. Before the advent of artificial colourings, blue pigments were made from minerals and blue dyes out of plants.

- [CMYKRed](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/cmykred.md): (static) The colour achieved in printing by mixing process magenta and process yellow in equal proportion. Also known as "Pigment Red". This shade is an approximation. Red is the last colour on the visible light spectrum. Red ochre pigments were among the first colours used by early humans and bright red pigments and dyes have been highly valued throughout history. Red pigments have been derived from minerals, plants and animals and used for art, cosmetics, architecture, pottery etc. Earth pigments may derive a red shade from iron, mercury, or lead. Plant and animal sources for red include the madder plant, resins of several genera, certain tree species, and cochineal and Kermes insects. Many of the natural sources were replaced by cheaper synthetic dyes after the advent of industrialisation. Symbolically red has been associated with e.g. courage, danger, sacrifice, passion, sexuality, love, happiness and good fortune. Evidence of humans using red ochre pigments dates back at least to the Late Stone Age and red was one of the first colours used by the earliest found human art, along with black and white. Evidence of the use of Kermes dyes dates back to the beginning of the Neolithic Period. Red pigments and dyes were popular in ancient cultures the world over. Some prominent examples include cosmetics in Egypt, red pottery in China and architecture in the Maya culture. In post-Antiquity Europe red became the colour of rulers and authority, as well as associated with the Christian Church, but it was also used by others to display wealth and power. In Chinese culture red became an important colour in the imperial hierarchy, with entire mansions of nobility painted red. In European art red remained a popular colour to signify nobility and importance. In the political upheavals from the French Revolution on, red became a popular colour to signify political radicalism or revolution, with for example socialist movements adopting the colour as their signifier. The first synthetic red pigment was developed in 1868, with others soon following.

- [Green](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/green.md): (static) Green is the colour between yellow and blue on the spectrum of visible light. In subtractive colour systems it is created by combining yellow and blue, in the RGB system it is one of the primary colours. The abundance of green in nature is due to Chlorophyll, light absorbing chemical which allows plants to use photosynthesis to absorb energy from sunlight. The word "green" is Germanic in origin and has ultimately been traced to a Proto Indo European root meaning "to grow". There is evidence of neolithic people in northern Europe using green clothing dye made out of birch leaves, but nothing to suggest green pigments were used in the art of the same period. In Ancient Egypt green was used in painting and dyeing, where it was associated with growth, health and rebirth. The Greeks of Classical Antiquity rarely used green in art, while the Romans associated green with the goddess Venus and used it widely. During the Middle Ages and the Renaissance when clothing colours were designated according to social rank the colour was associated with merchants, bankers and the gentry, however it took until 1500s for truly stable green dyes to be produced. From the 1700s onwards synthetic pigments and dyes were developed, which were brighter and stabler than earlier vegetable dyes, but often also toxic. Around the same time green became associated with the romantic movement, which sought inspiration from and celebrated nature. In the second half of the 1800s systematic study of colour theory arose and artists begun to use green to evoke specific emotions. Towards the end of 1900s the colour became associated with the environmental movement and political parties wishing to associate with it. Green is generally associated with spring, rebirth, youth, health, as well as calmness and the agreeable. The negative associations of green include envy, jealousy, poison or sickness. This is the colour defined as green in the CMYK colour system which is used in printing. The colour is achieved by mixing process (printer's) cyan with process (printer's) yellow in equal amounts. The shade indicated here is an approximation.

- [MunsellPurple](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/munsellpurple.md): (static) The intermediate colour between blue and red made by mixing the two shades. Differentiated from violet in that violet is defined as a spectral colour, whereas purple is defined as a mixed one. The earliest use of such colours dates back to the Neolithic, when manganese was ground up to be used as pigment in cave paintings. Purple dyes were produced in Dison and Tyre as early as the 15th century BCE. They were expensive and difficult to acquire and so the colour has been associated with royalty and power, as well as featured in many legends. Purple lost its position as a strictly imperial colour in Europe after the fall of Constantinople and was in time replaced by scarlet, procured from the cochineal insect. In ancient China purple was obtained from the plant purple gromwell. Purple remained expensive until the invention of aniline dyes in the 1800s. The word originally derives from the Greek word "porphura" which was the name of a dye manufactured in antiquity from a predatory sea snail. First recorded in English as a colour name in 975 CE.

- [NordicGreen](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/nordicgreen.md): (static) Green is the colour between yellow and blue on the spectrum of visible light. In subtractive colour systems it is created by combining yellow and blue, in the RGB system it is one of the primary colours. The abundance of green in nature is due to Chlorophyll, light absorbing chemical which allows plants to use photosynthesis to absorb energy from sunlight. The word "green" is Germanic in origin and has ultimately been traced to a Proto Indo European root meaning "to grow". There is evidence of neolithic people in northern Europe using green clothing dye made out of birch leaves, but nothing to suggest green pigments were used in the art of the same period. In Ancient Egypt green was used in painting and dyeing, where it was associated with growth, health and rebirth. The Greeks of Classical Antiquity rarely used green in art, while the Romans associated green with the goddess Venus and used it widely. During the Middle Ages and the Renaissance when clothing colours were designated according to social rank the colour was associated with merchants, bankers and the gentry, however it took until 1500s for truly stable green dyes to be produced. From the 1700s onwards synthetic pigments and dyes were developed, which were brighter and stabler than earlier vegetable dyes, but often also toxic. Around the same time green became associated with the romantic movement, which sought inspiration from and celebrated nature. In the second half of the 1800s systematic study of colour theory arose and artists begun to use green to evoke specific emotions. Towards the end of 1900s the colour became associated with the environmental movement and political parties wishing to associate with it. Green is generally associated with spring, rebirth, youth, health, as well as calmness and the agreeable. The negative associations of green include envy, jealousy, poison or sickness. This shade is the colour "green" from the Natural Colour System widely used in Scandinavia.

- [Ochre](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/ochre.md): (static) A group of natural earth pigments containing ferric oxide together with varying quantities of clay and sand. The colour of the pigment itself varies from yellow to deep orange or brown. The colours produced from these pigments take the pigment's name. Ochres are among the earth pigments used by early humans and archaeological evidence of use of their use dates back to the paleolithic throughout the world. Ochre pigments remained popular in art, architecture and household uses in the Mediterranean area through Antiquity, as well as in the Renaissance.

- [Orange](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/orange.md): (static) The colour between red and yellow on a colour wheel. The colour is named after the fruit orange. The original source of the word is the Sanskrit word "naranga". The word "orange" is first found in English as a colour name in 1512. Prior to the introduction of the word, expressions used in its place included "saffron", yellow-red or simply "red". Orange is a common colour in plants; in fruits and vegetables as well as in autumn leaves. Such colours are typically caused by carotenes, which are photosynthetic pigments. Orange pigments suitable for human use have been available since ancient times. They include mineral pigments such as orpiment and realgar, lead oxide pigments and plant dyes such as saffron and turmeric. Synthetic orange pigments include cadmium orange, a by-product of zinc mining and quinacridone orange, both commercially manufactured since the early 1900s. In Europe and America the colour is often associated with amusement and entertainment, with for example clown costumes prominently displaying the colour. In Asia it is often associated with spiritual ideas, such as transformation, illumination or people professionally engaged in religion. Politically orange may be associated with protestant Christianity, the Dutch royal house or European Christian Democrat parties, to name a few. The colour is easier to see in dim light or against water and is therefore also popular as a warning colour or as the colour of rescue equipment. This shade is from the RGB colour wheel.

Also known as "CMYK blue". The exact shade of the ink may vary depending on the formulation. Blue is one of the three primary colours in traditional colour theory and painting pigments, as well as in the RGB colour model. Blue has been an important colour throughout history, as lapis lazuli in jewellery and as a pigment, as cobalt blue in colouring porcelain, as woad and later indigo dyed clothing all the way to the modern synthetic pigments. Before the advent of artificial colourings, blue pigments were made from minerals and blue dyes out of plants. The pigment Egyptian Blue, made out of silica, lime, copper and alkalai in ancient Egypt, is commonly considered the first synthetic pigment. In the west blue is commonly associated with e.g. harmony, distance, calm or cold.
- [PigmentCyan](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/pigmentcyan.md): (static) Also known as "process cyan".

This shade is an approximation.
- [PigmentGreen](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/pigmentgreen.md): (static) Green is the colour between yellow and blue on the spectrum of visible light. In subtractive colour systems it is created by combining yellow and blue, in the RGB system it is one of the primary colours. The abundance of green in nature is due to Chlorophyll, light absorbing chemical which allows plants to use photosynthesis to absorb energy from sunlight. The word "green" is Germanic in origin and has ultimately been traced to a Proto Indo European root meaning "to grow". There is evidence of neolithic people in northern Europe using green clothing dye made out of birch leaves, but nothing to suggest green pigments were used in the art of the same period. In Ancient Egypt green was used in painting and dyeing, where it was associated with growth, health and rebirth. The Greeks of Classical Antiquity rarely used green in art, while the Romans associated green with the goddess Venus and used it widely. During the Middle Ages and the Renaissance when clothing colours were designated according to social rank the colour was associated with merchants, bankers and the gentry, however it took until 1500s for truly stable green dyes to be produced. From the 1700s onwards synthetic pigments and dyes were developed, which were brighter and stabler than earlier vegetable dyes, but often also toxic. Around the same time green became associated with the romantic movement, which sought inspiration from and celebrated nature. In the second half of the 1800s systematic study of colour theory arose and artists begun to use green to evoke specific emotions. Towards the end of 1900s the colour became associated with the environmental movement and political parties wishing to associate with it. Green is generally associated with spring, rebirth, youth, health, as well as calmness and the agreeable. The negative associations of green include envy, jealousy, poison or sickness. This is the colour defined as green in the CMYK colour system which is used in printing. The colour is achieved by mixing process (printer's) cyan with process (printer's) yellow in equal amounts. The shade indicated here is an approximation.
- [PigmentMagenta](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/pigmentmagenta.md): (static) Also known as "printer's magenta" and "process magenta". One of the three primary pigment colours used in colour printing. "pigment magenta" originates from the subtractive colour model (CMYK), and there's no fixed conversion from CMYK primaries to RGB. As different inks use different formulations, the exact shade of this colour can vary. The shade shown here a typical variant.
- [PigmentRed](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/pigmentred.md): (static) The colour achieved in printing by mixing process magenta and process yellow in equal proportion. Also known as "CMYK Red". This shade is an approximation. Red is the last colour on the visible light spectrum. Red ochre pigments were among the first colours used by early humans and bright red pigments and dyes have been highly valued throughout history. Red pigments have been derived from minerals, plants and animals and used for art, cosmetics, architecture, pottery etc. Earth pigments may derive a red shade from iron, mercury, or lead. Plant and animal sources for red include the madder plant, resins of several genera, certain tree species, and cochineal and Kermes insects. Many of the natural sources were replaced by cheaper synthetic dyes after the advent of industrialisation. Symbolically red has been associated with e.g. courage, danger, sacrifice, passion, sexuality, love, happiness and good fortune. Evidence of humans using red ochre pigments dates back at least to the Late Stone Age and red was one of the first colours used by the earliest found human art, along with black and white. Evidence of the use of Kermes dyes dates back to the beginning of the Neolithic Period. Red pigments and dyes were popular in ancient cultures the world over. Some prominent examples include cosmetics in Egypt, red pottery in China and architecture in the Maya culture. In post-Antiquity Europe red became the colour of rulers and authority, as well as associated with the Christian Church, but it was also used by others to display wealth and power. In Chinese culture red became an important colour in the imperial hierarchy, with entire mansions of nobility painted red. In European art red remained a popular colour to signify nobility and importance. In the political upheavals from the French Revolution on, red became a popular colour to signify political radicalism or revolution, with for example socialist movements adopting the colour as their signifier. The first synthetic red pigment was developed in 1868, with others soon following.
- [PigmentYellow](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/pigmentyellow.md): (static) One of the three main colours used in the subtractive colour system, along with magenta and cyan. As formulations of ink vary, there may be differences in the exact shade of the colour. Also known as "process yellow", "printer's yellow" or "canary yellow". On the visible light spectrum yellow falls between orange and green. One of the first pigments used by early humans was the earth pigment yellow ochre. It has for example been found in the 17 000 years old cave paintings of Lascaux. Yellow has historically been associated with gold and used to represent the metal in art. Yellow has been laden with multiple symbolical meanings through history, from reason and duplicity in Europe, to happiness, glory and the emperor in China, to wisdom in Islam and to divine essence in Polynesian religions, to name a few. In plants and some animals yellow colour is generated by carotenoids. The English word derives from Proto-Germanic word "gelwaz". This shade is the shade named as "canary yellow" in the British Standards for colours.

The English word derives from the name of Dianthus plumarius, or the common pink. In other European languages the colour is typically named after the flowering shrub genus Rosa. Pink is one of the most common colours of flowers. Different shades of pink became fashionable during the 1700s along with other pastel colours. The colour has been associated with both innocence and seduction. It didn't become solidly associated with girls and women until the 1900s. With the advent of industrially produced colours, pinks became stronger and bolder. First used as a colour name in English in the 1600s. This shade is from the "ISCC-NBS Dictionary of Color Names (1955)".

- [Purple](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/purple.md): (static) The intermediate colour between blue and red made by mixing the two shades. Differentiated from violet in that violet is defined as a spectral colour, whereas purple is defined as a mixed one. The earliest use of such colours dates back to the Neolithic, when manganese was ground up to be used as pigment in cave paintings. Purple dyes were produced in Dison and Tyre as early as the 15th century BCE. They were expensive and difficult to acquire and so the colour has been associated with royalty and power, as well as featured in many legends. Purple lost its position as a strictly imperial colour in Europe after the fall of Constantinople and was in time replaced by scarlet, procured from the cochineal insect. In ancient China purple was obtained from the plant purple gromwell. Purple remained expensive until the invention of aniline dyes in the 1800s.

- [Red](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/red.md): (static) Red is the last colour on the visible light spectrum. Red ochre pigments were among the first colours used by early humans and bright red pigments and dyes have been highly valued throughout history. Red pigments have been derived from minerals, plants and animals and used for art, cosmetics, architecture, pottery etc. Earth pigments may derive a red shade from iron, mercury, or lead. Plant and animal sources for red include the madder plant, resins of several genera, certain tree species, and cochineal and Kermes insects. Many of the natural sources were replaced by cheaper synthetic dyes after the advent of industrialisation. Symbolically red has been associated with e.g. courage, danger, sacrifice, passion, sexuality, love, happiness and good fortune. Evidence of humans using red ochre pigments dates back at least to the Late Stone Age and red was one of the first colours used by the earliest found human art, along with black and white. Evidence of the use of Kermes dyes dates back to the beginning of the Neolithic Period. Red pigments and dyes were popular in ancient cultures the world over. Some prominent examples include cosmetics in Egypt, red pottery in China and architecture in the Maya culture. In post-Antiquity Europe red became the colour of rulers and authority, as well as associated with the Christian Church, but it was also used by others to display wealth and power. In Chinese culture red became an important colour in the imperial hierarchy, with entire mansions of nobility painted red. In European art red remained a popular colour to signify nobility and importance. In the political upheavals from the French Revolution on, red became a popular colour to signify political radicalism or revolution, with for example socialist movements adopting the colour as their signifier. The first synthetic red pigment was developed in 1868, with others soon following.

- [UltramarineNatural](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/ultramarinenatural.md): (static) Ultramarine was originally a pigment obtained by grinding lapis lazuli into powder. Considered the finest blue pigment, ultramarine was the most expensive pigment used by Renaissance painters. Only the advent of synthetic ultramarine in 1826 finally brought down the price. Ultramarine, meaning "over the sea" comes from the fact that it had to be imported into medieval Europe from Afghanistan. The word was first recorded in English as a colour name in 1598. This is the shade named "ultramarine" in "Color Standards and Color Nomenclature" by Robert Ridgway (1912), and resembles the natural ultramarine pigment.
- [Umber](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/umber.md): (static) A brown or reddish brown natural earth pigment containing iron oxide and manganese oxide. Darker than the similar pigments ochre and sienna. The name "umber" refers to a specific earth pigment rather than a shade, thus umber can come in a range of different shades depending on the chemical composition of the clay used. The pigment is named after the Italian region of Umbria, where the pigment was originally produced. Umber is among the pigments found in neolithic art, along with other earth pigments and carbon. Umber and other dark earth pigments went out of favour during the Middle Ages, but became popular again during the Renaissance and Baroque, only to be again put aside by the impressionists. Not all modern pigments named "umber" contain natural earths. The shade shown here is one of several varieties of "umber" in the ISCC-NBS Dictionary of Color Names (1955).

- [Verdigris](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/verdigris.md): (static) The green pigment obtained from applying acetic acid to copper plates, or the colour of copper's natural patina. In oil paint verdigris is light fast, in other mediums it degrades. The pigment was obtained by exposing copper plates to acid such as vinegar and then scraping off the resulting patina. The patina may also be used to protect copper or bronze objects, such as statues from corrosion. Other uses have included fungicide, a chemical catalyst, dyeing or medicine. The name's origin is the Old French term "vert-de-Grèce" meaning "green of Greece". The pigment was used in paintings and other objects imported mostly from Greece. The exact colour of the pigment may vary. This shade is an approximation.
- [Vermilion](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/vermilion.md): (static) The colour of a bright red pigment made originally from the powdered mineral cinnabar, a mercuric sulphide. Vermilion was widely used in Ancient Rome, Middle Ages and Renaissance Europe, in India and in Chinese lacquerware. The word is derived from the Latin vermiculus, meaning small worm. The name was adopted as the colour was similar to the dye acquired from the insect Kermes vermilio. The exact hue of the pigment is determined by the size of the ground pigment particles. The pigment is a mercury compound and thus toxic. Originally "vermilion" was interchangeable with "cinnabar", but the former became the dominant term in the 18th century. The name vermilion was first recorded in English as a colour name in 1289. This shade is from "A Dictionary of Color" by Maerz and Paul (1930).

- [Violet](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/violet.md): (static) The colour at the end of the visible spectrum of light after blue. On the colour wheel violet is located between blue and purple. Technically violet is differentiated from purple in that the latter is defined to be a mixture of blue and red, while the former is defined with its own wavelengths. Violet is one of the oldest colours used, originally derived by grinding manganese, later from berries and plant juice. The earliest found examples are from prehistoric cave paintings and Neanderthal sites. Historically violet has, along with purple, been associated with royalty and power and worn by kings, high clergy or university professors. As with many other colours, good quality colour fast violet fabric was expensive and thus only used by the powerful. The colour name is derived from the Middle English and old French word "violette" along with the Latin "viola", which are names of the plant violet. The word was first recorded in English as a colour name in 1370. This shade is an approximation.

- [White](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/white.md): (static) The colour perceived when light stimulates all three types of colour cells in the human eye in equal measure and with relatively high brightness. White objects fully reflect all the visible wavelengths of light. Devoid of hue or greyness. White may symbolise purity, the good and cleanliness, but also simplicity, modernity or mourning. White was one of the colours used in prehistoric cave paintings with chalk or calcite providing the pigment. During the Renaissance a white pigment made of calcium carbonate and calcium hydroxide and named "Bianco di San Giovanni" was used. Until the end of the 1800s the most commonly used white pigment was lead white, made by corroding lead. The process was laborious and the pigment toxic. During the 1910s titanium white was developed, which had greater covering power and brightness than lead white. Another pigment in use is zinc white, made out of zinc oxide. It is similar to titanium white, but more transparent.

- [Yellow](https://developer.rhino3d.com/api/gh2/type/grasshopper2.eto.drawing.standardcolours/yellow.md): (static) One of the three main colours used in the subtractive colour system, along with magenta and cyan. As formulations of ink vary, there may be differences in the exact shade of the colour. Also known as "pigment yellow", "process yellow" or "canary yellow". On the visible light spectrum yellow falls between orange and green. One of the first pigments used by early humans was the earth pigment yellow ochre. It has for example been found in the 17 000 years old cave paintings of Lascaux. Yellow has historically been associated with gold and used to represent the metal in art. Yellow has been laden with multiple symbolical meanings through history, from reason and duplicity in Europe, to happiness, glory and the emperor in China, to wisdom in Islam and to divine essence in Polynesian religions, to name a few. In plants and some animals yellow colour is generated by carotenoids. The English word derives from Proto-Germanic word "gelwaz".
