The first recorded use of cerulean as a color name in English was in 1590. English is a West Germanic language originating in England and is the First language for most people in the United Kingdom, the United States [1] The word is probably derived from the Latin word caeruleus, "dark blue, blue or blue-green", which in turn probably derives from caelulum, diminutive of caelum, "heaven, sky". Latin ( lingua Latīna, laˈtiːna is an Italic language, historically spoken in Latium and Ancient Rome. [2]

In classical times, cerulean was used to describe blue pigments, particularly mixtures of copper and cobaltous oxides.

Copper (ˈkɒpɚ is a Chemical element with the symbol Cu (cuprum and Atomic number 29 Cobalt (ˈkoʊbɒlt is a hard lustrous silver-grey Metal, a Chemical element with symbol Co. An oxide is a Chemical compound containing at least one Oxygen atom as well as at least one other element These early attempts to create sky blue colors were often less than satisfactory due to greenish hues and lack of permanence. Hue is one of the main properties of a Color described with names such as " Red " " Yellow " etc Fugitive pigments, are Non-permanent Pigments - pigments that lighten in what is understood said or defined to be a relatively short time when exposed to light When the pigment 'cerulean blue' was invented, it largely superseded all these prior pigments.

Cerulean blue pigment

Discovered in 1805 by Andreas Höpfner, the pigment originally referred to as cerulean blue (or corruleum blue) was first marketed in 1860 as "coeruleum" by George Rowney of the United Kingdom. Year 1805 ( MDCCCV) was a Common year starting on Tuesday (link will display the full calendar of the Gregorian calendar (or Year 1860 ( MDCCLX) was a Leap year starting on Sunday (link will display the full calendar of the Gregorian Calendar (or a Leap year starting George Rowney is a UK supplier of Art materials now merged with the Daler Board Company to form Daler-Rowney Limited based in Bracknell Berkshire The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located The primary chemical constituent of the pigment is cobalt(II) stannate. Cobalt (ˈkoʊbɒlt is a hard lustrous silver-grey Metal, a Chemical element with symbol Co. The stannate Ion is Sn[[Oxygen O]]32&minus or Sn(O H)62&minus [3][4][5]

It is particularly valuable for artistic painting of skies because of the purity of the blue (specifically the lack of greenish hues), its permanence (no other blue pigments retained color as well), and its opaqueness. [6]

Today, cobalt chromate is sometimes marketed under the cerulean blue name but is darker and greener (Rex Art color index PB 36) than the cobalt stannate version (color index PB 35). Chromates and dichromates are Salts of Chromic acid and dichromic acid respectively The chromate makes excellent turquoise colors and is identified by Rex Art and some other manufacturers as "cobalt turquoise".
