 handprint : synthetic inorganic pigments
Use of chrome colors began to decline steadily in the 20th century because most shades contain lead and the light yellow shades are impermanent (they fade in light and flen when mixed with sulfur pigments), even after the introduction in the 1950's of more lightfast, silica encapsulated lead chromates.
All cobalt pigments are manufactured by calcining (roasting at extremely high temperatures) a mixture of cobalt oxide with an alkaline carbonate and, to produce the various colors, compounds of other metals (phosphorus, aluminum, tin, chromium, titanium, zinc or potassium); the resulting matrix is then ground into a fine powder.
The color was known in Europe as early as 1780, and used infrequently throughout the 19th century, mostly in watermedia paints.

 The Art of Fresco: Color
These colors are ground in water only and are, in most cases, the same colors that Giotto and Michelangelo and the early cave dwellers used.
The colors must be mineral, substances taken from the earth, as these alone will resist the alkaline action of the lime, which quickly works to destroy a color with a dye or stain base.
The mineral cobalt was known in early times but it was not until the 18th century that they knew how to extract it from the ore. Colors such as Prussian blue or the lakes fade under the bleaching action of the lime.

 Fool.com: Sun Adds Server Color With Cobalt [News] September 19, 2000
While Cobalt expands the size of Sun's addressable market, the deal also effectively ups the ante on the company's already large bet on an integrated architecture for servers.

Cobalt is a mirror-image of Sun in this regard, as the firm's strategy has been to provide its purpose-built hardware along with optimized Linux-based operating software, software applications, and middleware, such as bandwidth management and clustering technology.
