Editing Cyan (section)

==History ==
Cyan boasts a rich and diverse history, holding cultural significance for millennia. In ancient civilizations, [[turquoise]], valued for its aesthetic appeal, served as a highly regarded precious gem. Turquoise comes in a variety of shades from green to blue, but cyan hues are particularly prevalent.  Approximately 3,700 years ago, an intricately crafted dragon-shaped treasure made from over 2,000 pieces of turquoise and jade was created. This artifact is widely recognized as the oldest Chinese dragon totem by many Chinese scholars.<ref>{{Cite news |title=Archaeologists Find Oldest Chinese Dragon Totem |url=http://www.china.org.cn/english/features/Archaeology/147178.htm |date=2005-11-01 |access-date=2024-02-14 |agency=Xinhua News Agency}}</ref>

Turquoise jewelry also held significant importance among the [[Aztecs]], who often featured this precious gemstone in vibrant frescoes for both symbolic and decorative purposes. The Aztecs revered turquoise, associating its color with the heavens and sacredness.<ref>{{Cite web |url=https://azteczone.com/blogs/aztec-culture-articles/aztec-colors |title=What are the Aztec colors? |date=2023-08-12 |access-date=2024-02-14 |website=AZTECZONE |archive-date=2024-02-27 |archive-url=https://web.archive.org/web/20240227061331/https://azteczone.com/blogs/aztec-culture-articles/aztec-colors |url-status=usurped }}</ref> Additionally, ancient [[Egypt]]ians interpreted cyan hues as representing faith and truth, while [[Tibet]]ans viewed them as a symbol of infinity.<ref name="artandobject_com">{{Cite web |url=https://www.artandobject.com/news/allure-and-power-color-teal |title=The Allure and Power of the Color Teal |date=2022-06-21 |access-date=2024-02-21 |website=Art & Object |last=Parker |first=Dian}}</ref>

After earlier uses in various contexts, cyan hues found increased use in diverse cultures due to their appealing aesthetic qualities in religious structures and art pieces. For example, the prominent dome of the [[Goharshad Mosque]] in [[Iran]], built in 1418, showcases this trend. Additionally, [[Pontormo|Jacopo da Pontormo's]] use of a teal shade for [[Mary, mother of Jesus|Mary's]] robe in the 1528 painting ''[[Carmignano Visitation]]'' demonstrates the allure for these hues.<ref name="artandobject_com" /> During the 16th century, speakers of the English language began using the term ''[[turquoise (color)|turquoise]]'' to describe the cyan color of objects that resembled the color of the stone.<ref>Maerz and Paul (1930).

In the 1870s, the French sculptor [[Frédéric Bartholdi]] began the construction of what would later become the [[Statue of Liberty]]. Over time, exposure to the elements caused the copper structure to develop its distinctive [[patina]], now recognized as iconic cyan.<ref name="artandobject_com" />  Following this, there was a significant advancement in the use of cyan during the late 19th and early 20th centuries.

Impressionist artists, such as [[Claude Monet]] in his renowned ''[[Water Lilies]]'', effectively incorporated cyan hues into their works. Deviating from traditional interpretations of local color under neutral lighting conditions, the focus of artists was on accurately depicting perceived color and the influence of light on altering object hues. Specifically, daylight plays a significant role in shifting the perceived color of objects toward cyan hues.<ref>{{Cite web |url=https://www.khanacademy.org/humanities/becoming-modern/avant-garde-france/impressionism/a/impressionist-color |title=Impressionist color |access-date=2024-02-21 |website=Khan Academy |last1=Grant |first1=Kim |publisher=Google Classroom |last2=Cramer |first2=Charles |year=2021}}</ref> In 1917, the color term ''[[teal]]'' was introduced to describe deeper shades of cyan.<ref>Maerz and Paul (1930).

In the late 19th century, while ''traditional'' nomenclature of '''red''', '''yellow''', and '''blue''' persisted, the printing industry initiated a shift towards utilizing '''magenta''' and '''cyan''' inks for '''''red''''' and '''''blue''''' hues, respectively. This transition aimed to establish a more versatile color [[gamut]] achievable with only three primary colors.  In 1949, a document in the printing industry stated: “The '''four-color''' set comprises '''Yellow''', '''Red (magenta)''', '''Blue (cyan)''', '''Black'''”. This practice of labeling '''magenta''', '''yellow''', and '''cyan''' as '''''red''''', '''''yellow''''', and '''''blue''''' persisted until 1961.  As the hues evolved, the printing industry maintained the use of the ''traditional'' terms '''red''', '''yellow''', and '''blue'''. Consequently, pinpointing the exact date of origin for '''[[CMYK]]''', in which '''cyan''' serves as a primary color, proves ''challenging''.<ref>{{Cite journal |title=Semantic shift of the colour-terms ''maroon'' and ''magenta'' in British Standard English |journal=Revista de Lenguas para Fines Específicos |last=Wright |first=Laura |url=https://ojsspdc.ulpgc.es/ojs/index.php/LFE/article/view/121 |date=2011-11-27 |volume=17 |issue= |pages=341–376 }}</ref>

In August 1991, the HP Deskwriter 500C became the first Deskwriter to offer color printing as an option. It used interchangeable black and color (cyan, magenta, and yellow) inkjet print cartridges.<ref>{{Cite web |title=Twenty Years of Innovation: HP Deskjet Printers 1988 – 2008 |website=Hewlett-Packard |year=2008 |url=https://www.hp.com/hpinfo/newsroom/press_kits/2008/deskjet20/bg_deskjet20thannivtimeline.pdf}}</ref> With the inclusion of cyan ink in printers, the term "cyan" has become widely recognized in both home and office settings. According to TUP/Technology User Profile 2020, approximately 70% of online American adults regularly use a home printer.<ref>{{Citation |title=Home Printer Trends in the US |last=Ness |first=Dan |date=2021-02-25 |url=https://metafacts.com/home-printer-trends-in-the-us-tupdate/ |access-date=2024-04-21}}</ref>
