A '''color term''' (or color name) is a word or [[phrase]] that refers to a specific color. The color term may refer to human perception of that color (which is affected by visual context) which is usually defined according to the [[Munsell color system]], or to an underlying physical property (such as a specific [[wavelength]] on the [[spectrum]] of [[visible light]]). There are also numerical systems of color specification, referred to as [[color space]]s.

An important distinction must be established between color and shape, as these two attributes usually are used in conjunction with one another when describing in language. For example, they are labeled as alternative parts of speech terms color term and shape term.<ref name=":0">{{Cite book|title=Colour Categories in Thought and Language; 'The neuropsychology of color' |last=Davidoff |first=Jules |publisher=Press Syndicate of the University of Cambridge |year=1997 |isbn=9780521498005 |location=Cambridge, England |pages=118–120}}</ref>

Psychological conditions for recognition of colors exist, such as those who cannot discern colors in general or those who see colors as sound (a variety of [[synesthesia]]).

[[File:Colours in Irish.png|thumb|left|[[Color wheel]] with [[Irish language|Irish Gaelic]] colour terms, explaining that {{lang|ga|glas}} ("pale blue/grey/green") and {{lang|ga|gorm}} ("deep blue/grey/green") are distinguished based on intensity ([[luminosity]]) rather than [[hue]]. Similarly, {{lang|ga|buí}} refers not only to "yellow" and "gold", but pale browns as "buff beige" and "ochre", while {{lang|ga|dunn}} is for darker browns. {{lang|ga|Rua}} refers to red of hair ([[fox]], [[Erithacus rubecula|robin]]), whereas {{lang|ga|dearg}} refers to red of [[blood]] and {{lang|ga|bándearg}} is "pale red". Then, {{lang|ga|Bán}}, {{lang|ga|fionn}}, {{lang|ga|geal}}, and {{lang|ga|liath}} all refer to varying degrees of [[brightness]] or "fairness" — without mapping clearly only the English "white" — against {{lang|ga|dubh}} for "dark" or "black".]]

== Color dimensions ==
Typical human [[color vision]] is [[trichromatic]], meaning it is based on a three-dimensional color [[gamut]]. These three dimensions can be defined in different ways, but often the most intuitive definition are the dimensions of the [[HSL and HSV|HSL/HSV color space]]:

* '''[[Hue]]''': representing the different colors of the [[rainbow]] or [[color wheel]] (e.g. 'red', 'orange', 'yellow', etc.); roughly analogous to the color's [[wavelength]] or [[frequency]].
* '''[[Saturation (color theory)|Saturation]]''': the [[colorfulness]] of the color, i.e. a measure of vibrant vs. pale.
* '''[[Luminosity]]''': a measurement of intensity or 'brightness'.

==In natural languages==

===Lexicology===
[[wikt:monolexemic|Monolexemic]] color words are composed of individual [[lexeme]]s, or ''root words'', such as 'red', 'brown', 'fuchsia', or 'olive'. The root words generally describe the hue of the color, but some root words{{Mdash}}namely brown{{Mdash}}can also describe the other dimensions. Compound color words make use of prefix adjectives (e.g. 'light brown', 'sea green'), that generally describe the saturation or luminosity, or compounded basic color words (e.g. 'yellow-green'), which refine the hue of the color relative to root words. {{lang|fi|Vaaleanpunainen}}, the [[Finnish language|Finnish]] word for 'pink', is a clear [[agglutination]] of the language's words for 'pale' ({{lang|fi|vaalea}}) and 'red' ({{lang|fi|punainen}}).

=== Basic color terms ===
{{further|Basic Color Terms}}
Basic color terms meet the following criteria:<ref name="BerlinKay1969"/>
* monolexemic ('green', but not 'light green' or 'forest green'),
* high-frequency, and
* agreed upon by speakers of that language.

[[English language|English]] has 11 basic color terms: [[black]], [[white]], [[red]], [[green]], [[yellow]], [[blue]], [[brown]], [[Orange (colour)|orange]], [[pink]], [[purple]], and [[gray]]; other languages have between 2 and 12. All other colors are considered by most speakers of that language to be variants of these basic color terms. A useful [[litmus test (politics)|litmus test]] involves replacing each of these basic terms with an approximation of other basic terms, e.g. replacing orange with red-yellow. If the approximation is ''[[wikt:jarring#Adjective|jarring]]'', the replaced term likely meets the requirement for being a basic color term.
An example of a color that comes close to being a basic color term in English is ''turquoise''. It is monolexemic, but is not very high frequency, especially compared to alternatives teal or cyan. It also generally fails the above litmus test in that most people do not find the use of the approximation of other basic color terms (blue-green) to be jarring.

===Color-term hierarchy===
In the classic study of [[Brent Berlin]] and [[Paul Kay]] (1969), ''[[Basic Color Terms|Basic Color Terms: Their Universality and Evolution]]'',<ref name="BerlinKay1969"/> the researchers argued that the differences in number of basic color terms in languages follow a repeatable pattern. Color terms can be organized into a coherent hierarchy and there are a limited number of universal '''basic color terms''' which begin to be used by individual cultures in a relatively fixed order. This order is defined in stages I to VII. Berlin and Kay originally based their analysis on a comparison of color words in 20 languages from around the world. The model is presented below, broken into stages, with stage I on the left and stage VII on the right:<ref>{{cite journal |last1=Kay |first1=Paul |last2=McDaniel |first2=Chad |year=1978 |title=The Linguistic Significance of the Meanings of Basic Color Terms |journal=Language |volume=54 |issue=3 |pages=610–646 |doi=10.1353/lan.1978.0035|s2cid=26961780 }}</ref><br/><math>\begin{Bmatrix}\text{white} \\ \text{black} \end{Bmatrix} < \text{red} < \begin{Bmatrix}\text{green} \\ \text{yellow} \end{Bmatrix} < \text{blue} < \text{brown} <\begin{Bmatrix}\text{purple} \\ \text{pink} \\ \text{orange} \\ \text{grey} \end{Bmatrix}</math>

Berlin and Kay's study identified seven stages of color distinction systems. Each progressive stage features a color term that the previous stages do not.

====Stage I (dark and light)====

! style="font-weight:normal;" | light–warm (white/yellow/red)<br/>dark–cool (black/blue/green)
|}
Stage I contains two terms, white and black (light and dark); these terms are referenced broadly to describe other undefined color terms. For example, the [[Yali people|Yali]] highland group in New Guinea identify the color of blood as black. This is because blood, as a relatively dark liquid, is grouped into the same color classification as black.

In the [[Bassa language]], there are two terms for classifying colors: {{lang|bsq|ziza}} (white, yellow, orange, and red) and {{lang|bsq|hui}} (black, violet, blue, and green).<ref>{{cite journal |last1=McNeill |first1=N. B. |title=Colour and colour terminology |journal=Journal of Linguistics |date=28 November 2008 |volume=8 |issue=1 |pages=21–33 |doi=10.1017/S002222670000311X|s2cid=26668333 }}</ref>

In the [[Pirahã language]], there appear to be no color terms beyond describing lightness and darkness.<ref>Kay, Paul. (2007). [http://itre.cis.upenn.edu/myl/languagelog/archives/004399.html ''Pirahã Color Terms'']. Retrieved 17 March 2019.</ref>

The [[Grand Valley Dani|Dani language]] of [[western New Guinea]] differentiates only two basic colors: {{lang|dni|mili}} for cool/dark shades such as blue, green, and black; and {{lang|dni|mola}} for warm/light colors such as red, yellow, and white.<ref>{{Cite book|url=https://books.google.com/books?id=Fl8gAQAAIAAJ&q=mili+mola++|title=The Invention of Basic Colour Terms|first=Barbara Ann Christine|last=Saunders|year=1992|publisher=R.U.U.–I.S.O.R.|isbn=9789051870879 |via=Google Books}}</ref><ref>{{Cite journal|url=http://www.jstor.org/stable/2800917|title=Probabilities, Sampling, and Ethnographic Method: The Case of Dani Colour Names|author=Heider, Eleanor Rosch|year=1972|journal=Man|volume=7|issue=3|pages=448–466|doi=10.2307/2800917|jstor=2800917 }}</ref>

====Stage II (red)====

|-
! style="background-color:#c0c0c0;" | Stage II<ref name=Kay99/>
! style="font-weight:normal;" | white<br/>red/yellow<br/>black/blue/green
|}
Stage II implements a third term for red. Objects begin to rely less on their brightness for classification and in this stage we instead see each term cover a larger scope of colors. Specifically, blue and other darker shades continue to be described as black, yellow and orange colors are classified with red, and other bright colors continue to be classified with white.

In the [[Bambara language]], there are three color terms: {{lang|bm|dyema}} (white, beige), {{lang|bm|blema}} (reddish, brownish), and {{lang|bm|fima}} (dark green, indigo, and black).

====Stage III/IV (yellow + green)====
{| class="wikitable" style="font-weight:bold; float:right"

! style="font-weight:normal;" |white<br/>red/yellow<br/>green/blue<br/>black
|}
Stage III identifies a third term referring either to green (IIIa) or yellow (IIIb). Most languages in the study with this system identify yellow over green, such as the [[Komi language]], where green is considered a shade of yellow ({{lang|kv|виж}}, {{lang|kv|vizh}}), called {{lang|kv|турун виж}} ({{lang|kv|turun vizh)}} {{Gloss|grass yellow}}.<ref>Rueter, Jack M. (1996), Komia-anglisköĭ-finsköĭ</ref> However, the Nigerian [[Ibibio language]] and the Philippine [[Hanunoo language]] both identify green instead of yellow.

The [[Ovahimba]] use [[Himba people#Color perception and vision|four color names]]: {{lang|hz|zuzu}} stands for dark shades of blue, red, green, and purple; {{lang|hz|vapa}} is white and some shades of yellow; {{lang|hz|buru}} is some shades of green and blue; and {{Lang|hz|dambu}} is some other shades of green, red, and brown.<ref name="himba colour">{{cite book |last1=Roberson |first1=Debi |last2=Davidoff |first2=Jules |last3=Davies |first3=Ian R.L. |last4=Shapiro |first4=Laura R. |year=2006 |chapter=Colour categories and category acquisition in Himba and English |pages=159–172 |publisher=John Benjamins Publishing Company |doi=10.1075/z.pics2.14rob |editor1-first=Nicola |editor1-last=Pitchford |editor2-first=Carole P. |editor2-last=Biggam |title=Progress in Colour Studies |volume=II Psychological aspects |isbn=978-90-272-3240-3 |via=ResearchGate |chapter-url=https://www.researchgate.net/publication/43627151 |access-date=2012-05-28}}</ref> It is thought that this may [[Stroop effect|increase the time it takes]] for the Ovahimba to distinguish between two colors that fall under the same [[Herero people|Herero]] color category, compared to people whose language separates the colors into two different color categories.<ref>{{cite journal |last1=Reiger |first1=Terry |first2=Paul |last2=Kay |title=Language, thought, and color: Whorf was half right |journal=[[Trends (journals)|Trends in Cognitive Sciences]] |date=28 August 2009 |doi=10.1016/j.tics.2009.07.001 |url=http://www1.icsi.berkeley.edu/~kay/tics2.pdf |access-date=2012-08-29 |volume=13 |issue=10 |pages=439–446 |pmid=19716754|s2cid=2564005 }}</ref>

Stage IV incorporates green or yellow, whichever was not already present, i.e. stage IIIa languages will adopt yellow and stage IIIb languages will adopt green. Most stage IV languages continue to [[colexification|colexify]] blue and green, as listed in ''[[Blue–green distinction in language]]''.

The [[Chinese character]] [[wikt:青|青]] (pronounced {{lang|cmn-Latn|qīng}} in [[Standard Chinese|Mandarin]] and {{lang|ja-Latn|ao}} in Japanese) has a meaning that covers both blue and green. In more contemporary terms, they are [[wikt:藍|藍]] ({{lang|cmn-Latn|lán}}, in Mandarin) and [[wikt:綠|綠]] ({{lang|cmn-Latn|lǜ}}, in Mandarin) respectively. Japanese also has two terms that refer specifically to the color green, {{wikt-lang|ja|緑}} ({{lang|ja-Latn|midori}}, derived from the classical Japanese descriptive verb {{lang|ja-Latn|midoru}} {{Gloss|to be in leaf, to flourish}} in reference to trees) and {{lang|ja|グリーン}} ({{lang|ja-Latn|guriin}}, which is derived from the English word 'green').{{Citation needed|date=January 2017}}

====Stage V (blue)====

! style="background-color:#c0c0c0;" | Stage V<ref name=Kay99/>
! style="font-weight:normal;" |white<br/>red<br/>yellow<br/>green<br/>blue<br/>black
|}
Stage V introduces blue as its own color term, differentiating from black or from green.

====Stage VI (brown)====
The seventh basic color term is likely to be brown.

In English, this is the first basic color term (other than black and white) that is not differentiated on hue, but rather on lightness. English splits some hues into several distinct colors according to lightness: such as red and pink or orange and brown. To English speakers, these pairs of colors, which are objectively no more different from one another than light green and dark green, are conceived of as belonging to different categories.<ref name="BerlinKay1969">{{cite book |author1-link=Brent Berlin |last1=Berlin |first1=Brent |author2-link=Paul Kay |first2=Paul |last2=Kay |year=1969 |title=Basic Color Terms: Their universality and evolution |title-link=Basic Color Terms: Their Universality and Evolution}}</ref>

====Stage VII====
Stage VII adds additional terms for orange, pink, purple, or gray, but these do not exhibit the same hierarchy as the previous seven colors.<ref>{{cite book |editor-last=Varley |editor-first=Helen |title=Color |location=London |date=1980 |publisher=Marshall Editions |isbn=0-89535-037-8 |chapter=The Vocabulary of Color |pages=50–51}}</ref> 

English contains eleven basic color terms: 'black', 'white', 'red', 'green', 'yellow', 'blue', 'brown', 'orange', 'pink', 'purple', and 'gray'.

====Stage VII+====
[[File:Moscow-metro-light-blue-line.png|thumb|Use of light-blue ({{lang|ru|голубой}}, {{lang|ru-Latn|{{Itco|goluboi}} }}) and dark-blue ({{lang|ru|синий}}, {{lang|ru-Latn|{{Itco|sinii}} }}) colors for different lines of the [[Moscow Metro]]]]
Languages with further color distinction use relativistic light/dark terms like light blue{{Nbsp}}/ [[navy blue|dark blue]] (in comparison to blue sky{{Nbsp}}/ blue ocean), or [[pink|pale red]]{{Nbsp}}/ [[Maroon|deep red]].

[[Italian language|Italian]], [[Russian language|Russian]] and [[Hebrew language|Hebrew]] have twelve basic color terms, each distinguishing blue and light blue. A Russian will make the same red/pink and orange/brown distinctions, but will also make a further distinction between {{lang|ru|синий}} ({{lang|ru-Latn|sinii}}) and {{lang|ru|голубой}} ({{lang|ru-Latn|goluboi}}), which English speakers would call dark and light blue. To Russian speakers, {{lang|ru-Latn|sinii}} and {{lang|ru-Latn|goluboi}} are as separate as red and pink, or orange and brown.<ref>{{cite news |title=Seeing the blues |magazine=Nature |series=News |date=2007-04-30 |url=http://www.nature.com/news/2007/070430/full/news070430-2.html}}</ref>

[[Hungarian language|Hungarian]] and [[Turkish language|Turkish]] [[Hungarian language#Two words for "red"|distinguish multiple words]] for 'red': {{lang|hu|piros}} and {{lang|hu|vörös}} (Hungarian; {{lang|hu|vörös}} is a darker red), and {{lang|tr|kırmızı}}, {{lang|tr|al}}, and {{lang|tr|kızıl}} (Turkish); {{lang|tr|kırmızı}} now includes all reds but originally referred to [[crimson]], to which it is cognate, while {{lang|tr|kızıl}} mainly refers to scarlet and other orange-tinted or brownish reds. Two words for 'red' are also found in Irish and [[Scottish Gaelic]]: ({{lang|ga|dearg}} for light, bright red and {{lang|ga|rua}} or {{lang|gd|ruadh}} respectively for dark, brownish red). Turkish also has two words for 'white' ({{lang|tr|beyaz}} and {{lang|tr|ak}}) and 'black' ({{lang|tr|siyah}} and {{lang|tr|kara}}). {{lang|tr|Ak}} and {{lang|tr|beyaz}} have the same meaning, while {{lang|tr|kara}} is a broader term than {{lang|tr|siyah}} and also includes dark browns; which word is used also depends on the kind of object being described. Both {{lang|tr|ak}} and {{lang|tr|kara}} are of Turkic origin, while {{lang|tr|siyah}} is borrowed from [[Persian language|Persian]], and {{lang|tr|beyaz}} from Arabic {{lang|ar|بياض}} {{lang|ar-Latn|bayāḍ}}.

In [[Serbo-Croatian]] there are differences in dark brown ({{lang|sh|mrk}}), brown ({{Lang|sh|smeđ}} and {{lang|sh|kestenjast}}), red ({{lang|sh|crven}}), pink ({{lang|sh|ružičast}}), and orange ({{lang|sh|narandžast}}), as well as in blue hues: navy blue ({{lang|sh|teget}}), dark blue ({{lang|sh|modar}}), blue ({{lang|sh|plav}}), and ash blue ({{lang|sh|{{Itco|sinj}} }}).

An interesting case that deviates from this pattern is [[Irish language|Irish]]'s two words for green:
* {{lang|ga|glas}} denotes the green color of plants
* {{lang|ga|uaine}} denotes artificial greens of dyes, paints etc.
This distinction is made even if two shades are identical. {{Lang|ga|Glas}} is also used for "natural" grays, such as the [[Eastern gray squirrel|gray squirrel]], {{lang|ga|iora glas}}.<ref>{{Cite web |url=https://www.thejournal.ie/readme/the-irish-for-colours-you-may-have-forgotten-lots-of-your-schooling-but-you-should-remember-the-word-bandearg-4447647-Jan2019/ |title=The Irish For: How many colours can you remember? |first=Darach |last=Ó Séaghdha |date=January 20, 2019 |work=[[TheJournal.ie]] }}</ref><ref>{{Cite web |url=https://books.google.com/books?id=gnQ9AAAAYAAJ&q=uaine+glas+distinction |title=Transactions of the Gaelic Society of Glasgow |via=[[Google Books]] }}</ref>

====Linguistic relativity====
{{main|Linguistic relativity and the color naming debate}}
These colors roughly correspond to the sensitivities of the retinal ganglion cells, leading Berlin and Kay to argue that color naming is not merely a cultural phenomenon, but is one that is also constrained by biology—that is, language is shaped by perception.<ref name="BerlinKay1969"/> A 2012 study<ref>{{cite journal |last1=Loreto |first1=Vittorio |last2=Mukherjee |first2=Animesh |last3=Tria |first3=Francesca |year=2012 |title=On the origin of the hierarchy of color names |journal=Proceedings of the National Academy of Sciences |volume=109 |issue=18 |pages=6819–6824 |doi=10.1073/pnas.1113347109 |pmc=3344991 |pmid=22509002|bibcode=2012PNAS..109.6819L |doi-access=free }}</ref> suggested that the origin of this hierarchy may be tied to human vision and the time ordering in which these color names get accepted or agreed upon in a population perfectly matches the order predicted by the hierarchy.

=== Non-hue terms ===
This article mostly describes the color terms that define the ''hue'' of a color, since hue is considered the most innate dimension of the three. However, other terms are often used to describe the other two dimensions, which can be seen as common prefixes to the root terms that generally describe hue. Adding prefixes to root color terms generates [[wikt:multilexemic|multilexemic]] colors. Examples of common prefix adjectives can be seen in a [[List_of_colors_(compact)|list of color names]] and are described:
* [[Brightness]]: can describe either high luminosity or high saturation, according to the [[Helmholtz–Kohlrausch effect]] and/or [[Hunt effect (color)|Hunt effect]].
* [[Lightness]]: describes both a high luminosity ''and'' low saturation
* [[Darkness]]: the opposite of lightness, or low luminosity
* [[Paleness (color)|Paleness]], ''dullness'': a measure of desaturation
* [[wikt:deep#Adjective|Deep]], [[Royal blue|Royal]]: may refer to darkness and/or high saturation; unrelated to [[color depth]].
* [[Colorfulness#Excitation purity|Pure]], ''Bold'', [[wikt:vivid|Vivid]], [[wikt:rich#Adjective|Rich]]: all referring to high saturation
* [[Pastel (color)|Pastel]]: refers to colors with high luminosity and low saturation.
* [[wikt:neon#Adjective|Neon]]: bright, in either of the word's connotations; alluding to the bright glow of [[neon lighting]].
* [[fluorescence|Fluorescent]]: very bright, sometimes also highly saturated. Named after the [[fluorescence]] effect of [[pigment]]s and [[dye]]s, which can produce a luminous glow when viewed under [[ultraviolet|ultraviolet light]], thereby appearing significantly brighter than their surroundings.<ref>{{cite magazine |first=David |last=Schoonmaker |date=May–June 2006 |title=Sunshine on a cloudy day |magazine=American Scientist |volume=94 |number=3 |page=217 |doi=10.1511/2006.59.217 |url=https://www.americanscientist.org/article/sunshine-on-a-cloudy-day}}</ref>

=== Non-dimensional terms ===
Other terms sometimes used to describe color are related to physical phenomenon that do not describe a single color, but describe the dynamic nature of an object's color. These include:
* [[Gloss (optics)|Glossy]]: whether the surface reflects ''diffusely'' or ''specularly'' (sharply)
* [[Metallic color|Metallic]]: distinguishing 'gold' and 'silver' from shades of 'yellow' and 'gray', respectively
* [[Iridescence|Iridescent]]: dependence of color on viewing angle, innate to [[structural coloration]]
* [[opacity (optics)|Opacity]]: opaque (solid) vs. translucent (transparent or see-through)

=== Abstract and descriptive color terms ===
Color terms can be classified as ''abstract'' or ''descriptive'', though the distinction is often unclear.

'''Abstract''' color terms refer only to the color they represent and any etymological link to an object of that color is lost. In English white, black, red, yellow, green, blue, brown, and gray are abstract color terms. These terms are also ''basic color terms'' (as described above), though other abstract terms like [[maroon]] and [[magenta]] are not considered basic color terms.

'''Descriptive''' color terms are secondarily used to describe a color but primarily refer to an object or phenomenon. 'Salmon', 'rose', 'saffron', and 'lilac' are descriptive color terms in English because their use as color terms is derived in reference to natural colors of [[salmon]] flesh, [[rose]] flowers, infusions of [[saffron]] pistils, and [[lilac]] blossoms respectively.

Abstract color terms in one may be represented by descriptive color terms in another; for example in Japanese pink is {{lang|ja-Latn|momoiro}} ({{lang|ja|桃色}}, {{Lit|peach-color}}) and gray is either {{lang|ja-Latn|haiiro}} or {{lang|ja-Latn|nezumiiro}} ({{lang|ja|灰色}}, {{lang|ja|鼠色}}, lit. 'ash-color' for light grays and 'mouse-color' for dark grays respectively). Nevertheless, as languages evolve they may adopt or invent new abstract color terms, as Japanese has adopted {{lang|ja-Latn|pinku}} ({{lang|ja|ピンク}}) for pink and {{lang|ja-Latn|gurē}} ({{lang|ja|グレー}}) for gray from English.

While most of the 11 basic color terms in English are decidedly abstract, three of them (all stage VII, so understandably the youngest basic color terms) are arguably still descriptive:
* ''Pink'' was originally a descriptive color term derived from the name of a [[dianthus|flower called a 'pink']]. However, because the word 'pink' is rarely used to refer to the flower anymore, relative to its common usage as a color, it is often regarded as an abstract color term.
* ''Purple'' is another example of this shift, as it was originally a word that referred to the [[dye]] named [[Tyrian purple]], which took its name from the Latin {{lang|la|purpura}}, which referred to both the dye and the [[sea snail]] from which the dye was derived. However, this etymological link has been lost in translation.
* ''[[Orange (word)|Orange]]'' is difficult to categorize as abstract or descriptive because both its uses, as a color term and as a word for an object, are very common and it is difficult to distinguish which of the two is primary. As a basic color term it became established in the early-to-mid 20th century;{{Citation needed|date=March 2024}} before that time artist's palettes called it 'yellow-red'. In English, the use of the word 'orange' for a fruit predates its use as a color term. The word comes from French {{lang|fr|orenge}}, which derives via [[Arabic]] {{wikt-lang|ar|نارنج}} ({{lang|ar-Latn|nāranj}}) and [[Sanskrit]] {{wikt-lang|sa|नारङ्ग}} ({{lang|sa-Latn|nāraṅga}}) from a [[Dravidian languages|Dravidian language]] such as [[Tamil language|Tamil]] or [[Tulu language|Tulu]].<ref>{{Cite encyclopedia |date=June 2012 |title=orange, n.1 and adj.1 |encyclopedia=[[Oxford English Dictionary]] |publisher=[[Oxford University Press]] |url=http://www.oed.com/view/Entry/132163 |access-date=2012-09-04}}</ref> The derived form ''orangish'' as a color is attested from the late 19th century<ref>''[[Oxford English Dictionary]],'' 'orangish'</ref> by reference to the fruit.

==Struggle in linguistics==
{{Technical|section|date=October 2022}}
Research on color terms is often conducted without reference to common uses of the term or its significance within the context of its original language. In [[John A. Lucy]]'s article ''The linguistics of 'colour{{'}}'' he identifies two key categories. One of these is "[[characteristic referential range]]", or the use of a color term to identify or differentiate a referent over a wide context.<ref name=":0" />

== Philosophy ==

Color objectivism holds that colors are objective, mind-independent properties of material objects or light sources and that color terms refer to objective reality. Two main forms are color primitivism, which sees colors as simple, irreducible qualities either realist or eliminativist, and color physicalism, which views colors as objective properties that require empirical investigation to understand. Color irrealism, eliminativism or fictionalism denies that material objects and light sources actually possess colors, though eliminativists may describe colors as dispositions or attributes of sensations, as seen in the work of [[Descartes]], [[Isaac Newton|Newton]], and others. Color dispositionalism sees colors as dispositional properties, existing as powers to cause color experiences in perceivers using the right conditions.<ref>{{Citation |last1=Maund |first1=Barry |contribution=Color |title=The Stanford Encyclopedia of Philosophy |edition=Fall 2024 |editor-last1=Zalta |editor-first1=Edward N. |editor-last2=Nodelman |editor-first2=Uri |url=https://plato.stanford.edu/archives/fall2024/entries/color/ }}</ref> Averill's radical relationism argues that colors are relational properties. He suggests that the color term "yellow", for example, is a relational term tied to both populations of normal observers and optimal viewing conditions in specific environments.<ref>{{Citation |last1=Averill |first1=Edward Wilson |title=The Relational Nature of Color |journal=Philosophical Review |volume=101 |issue=3 |pages=551–588 |year=1992 |doi=10.2307/2186057 }}</ref>

For [[Wittgenstein]], in his work [[Remarks on Colour]], any puzzles about color and color terms can only be resolved through attention to the [[language games]] involved. He stated that our description of colors are neither fully [[empirism|empirical]] nor [[a priori]]. Statements such as "there cannot be a reddish green" are taken as a part of a [[logic]]al structure akin to geometry, institing that color-related terms and propositions are rooted in our language practices.

[[Frank Cameron Jackson|Frank Jackson]]'s [[knowledge argument]] against [[physicalism]] involves a famous thought experiment about Mary, a scientist knowing everything about the physical aspects of color, including physics and terms, but has lived her whole life in a black-and-white room. When Mary leaves the room and experiences color for the first time, she learns what it feels like to see color, i.e., acquires certain [[qualia]] while using the color term "red", suggesting subjective aspects of color experience.

The [[inverted spectrum]] argument states that two people could experience different subjective experiences while seeing the same color even when using the same color term "red". For example, one person might see red as what the other experiences as green, even though they both use the color term "red".

Hardin addresses the everyday color terms like "red", "yellow", "green", and "blue", as essential reference points in the study of color. He explores what elements of color are fundamental versus accidental, emphasizing his focus on a core set of colors, including white, black, and gray, while acknowledging a special place for brown in color perception.<ref>{{Citation |last1=Hardin |first1=Clyde L. |title=Color for Philosophers: Unweaving the Rainbow|publisher=Hackett  |year=1993 }}</ref> Peacock explores the relationship between how we conceptualize colors and how we experience them, examining whether color concepts, shaped by language and cognition, align with our subjective experience of color perception.<ref>{{Citation |last1=Peacocke |first1=Christopher |title=Colour Concepts and Colour Experience |journal=Synthese |volume=58 |issue=3 |pages=365–381 |year=1984 |publisher=Springer Nature}}</ref> 

For Foster, color constancy refers to the phenomenon where the perceived color of a surface remains stable despite changes in lighting conditions, such as intensity or spectral composition. <ref>{{Citation |last1=Foster |first1=David H. |title=Does Colour Constancy Exist? |journal=Trends in Cognitive Sciences |volume=7 |issue=10 |pages=439–443 |year=2003 |doi=10.1016/j.tics.2003.08.002}}</ref> Txapartegi analyzed how the ancient Greeks understood and categorized color through the concepts of hue, brightness, and saturation, using color terms from classical Greek texts.<ref>{{Citation |last1=Txapartegi |first1=E. |contribution=Hue, Brightness & Saturation in Classical Greek Chroma Terms |title=How Colours Matter to Philosophy |volume=388 |series=Synthese Library |editor-last=Silva |editor-first=Marcos |publisher=Springer |location=Cham |year=2017 |doi=10.1007/978-3-319-67398-1_2 }}</ref> 

Šekrst and Karlić introduced cognitive convenience, referring to naming of objects of a certain color, for which their hue is not as important as their brightness. For example, in various languages, grapes are described using color terms "white" and "black" even though their real hue is usually a  certain shade of green or purple.<ref>{{Citation |last1=Šekrst |first1=Kristina |last2=Karlić |first2=Virna |title=Red Onions are Clearly Purple: Cognitive Convenience in Color Naming |journal=Communication and Culture Online |volume=15 |issue=15 |year=2024|url=https://philpapers.org/rec/SEKROA-2}}</ref> Hansen and Chemla explore whether color adjectives, like "red" or "green", function as relative or absolute adjectives, using experimental methods instead of informal judgments. Their findings reveal interpersonal variation in how people apply color adjectives, challenging existing theories and highlighting the complexity of scalar adjectives and context sensitivity.<ref>{{Citation |last1=Hansen |first1=Nat |last2=Chemla |first2=Emmanuel |title=Color Adjectives, Standards, and Thresholds: An Experimental Investigation |journal=Linguistics and Philosophy |volume=40 |issue=3 |pages=1–40 |year=2017|url=https://philpapers.org/rec/HANCAS-2}}</ref>

Decock analzyes conceptual change and engineering in the context of color concepts, arguing that in the case of conceptual change of colour concepts varying degrees of optimization, design and control are possible.<ref>{{Citation |last1=Decock |first1=Lieven |title=Conceptual Change and Conceptual Engineering: The Case of Colour Concepts |journal=Inquiry: An Interdisciplinary Journal of Philosophy |volume=64 |issue=1-2 |pages=168–185 |year=2021|url=https://philpapers.org/rec/DECCCA-2}}</ref> Krempel investigates whether differences in color terminology across languages lead to differences in color experience, questioning whether language can penetrate and affect perception. She argues that empirical studies do not conclusively support the idea of linguistic penetrability in color experience, even if differences exist between speakers of different languages.<ref>{{Citation |last1=Krempel |first1=Raquel |title=Is Color Experience Linguistically Penetrable? |journal=Synthese |volume=199 |issue=1-2 |pages=4261–4285 |year=2021}}</ref>

==Standardized systems==
In contrast with the color terms of natural language, systematized color terms also exist. Some examples of color-naming systems are [[Color Naming System|CNS]]<ref>{{Citation |last1=Berk |first1=T. |last2=Brownston |first2=L. |last3=Kaufman |first3 = A. |contribution=A New Color-Naming System for Graphics Languages |title=IEEE Computer Graphics and Applications |publisher=[[IEEE]] |volume=2 |pages=37–44 |year=1982 }}</ref> and [[ISCC–NBS system|ISCC–NBS]] lexicon of color terms. The disadvantage of these systems, however, is that they specify only specific color samples, so while it is possible to, by interpolating, convert any color to or from one of these systems, a lookup table is required. In other words, no simple invertible equation can convert between [[CIE XYZ]] and one of these systems.

[[Philately|Philatelists]] traditionally use names to identify [[postage stamp color]]s. While the names are largely standardized within each country, there is no broader agreement, and so for instance the US-published [[Scott catalogue]] will use different names than the British [[Stanley Gibbons]] catalogue.

On modern computer systems a standard set of basic color terms is now used across the [[web colors|web color names]] (SVG 1.0/CSS3), [[HTML color names]], [[X11 color names]] and the [[.NET Framework]] color names, with only a few minor differences.

The [[Crayola]] company is famous for its many [[list of Crayola crayon colors|crayon colors]], often creatively named.

[[Heraldry]] has standardized names for '[[Tincture (heraldry)|tincture]]s', subdivided into 'colors', 'metals', and 'furs'.
