International Klein Blue (or IKB as it is known in art circles) was developed by French artist Yves Klein as part of his search for colors which best represented the concepts he wished to convey as an artist. [He was fascinated by mystical ideas, by notions of the infinite, the undefinable, the absolute.] He patented this color in 1960. IKB was developed by Klein and chemists to have the same color brightness and intensity as dry pigments, which it achieves by suspending dry pigment in polyvinyl acetate, a synthetic resin.
In 2008, the artist Roger Hiorns filled an abandoned waterproofed council flat in London with 75,000 liters of copper sulfate solution. The solution was left to crystallize for several weeks before the flat was drained, leaving crystal-covered walls, floors and ceilings. The work is titled Seizure. He went on to win the Turner prize that year.

Copper sulfate is also used to test blood for anemia; it is is also used to etch zinc plates for intaglio printmaking.
Maybe our love affair with blue is as easy to understand as our love for the blue skies of day light and the deep blue of a starlit night. Bayer's Uranometria, is one of the most important celestial atlases of the 17th Century.
