Cerulean (/səˈruːliən/), also spelled caerulean, is a color term that may be applied to certain colors with the hue ranging roughly between blue and cyan, overlapping with both. It also largely overlaps with azure and sky blue, although cerulean is dimmer.

The first recorded use of cerulean as a color name in English was in 1590.[2] The word is derived from the Latin word caeruleus, "dark blue, blue or blue-green", which in turn probably derives from caerulum, diminutive of caelum, "heaven, sky".[3]

Use in artistic painting

Cerulean blue PB35
A sample swatch of cerulean blue hue oil paint. 'Hue' in this case means that other pigments have been used to mimic the hue of oil paint containing the original pigment.

In classical times, cerulean was used to describe blue pigments, particularly mixtures of copper and cobaltous oxides. These early attempts to create sky blue colors were often less than satisfactory due to greenish hues and lack of permanence. When the pigment cerulean blue (shown in the color box to the left) was invented, it largely superseded all these prior pigments. See also Tekhelet.

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. The primary chemical constituent of the pigment is cobalt(II) stannate.[8][9][10]

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.[11] Berthe Morisot painted the blue coat of the woman in her "A Summer's Day', 1879 in cerulean blue in conjunction with artificial ultramarine and cobalt blue.[12]

Berthe Morisot, A Summer's Day, 1879

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). The chromate makes excellent turquoise colors and is identified by Rex Art and some other manufacturers as "cobalt turquoise".[13][14]
