The origin of colours - A study on the history of pigments
Ever since man decided to use clay dust, burnt charcoal, and chalk some 40,000 years ago to depict animals on cave walls, colour has always had a special value, both symbolic and technological. To this day, the use of certain colours is strategic, even in the art world, as in the case of Yves Klein's blue, or Vantablack a new technology that creates the darkest surface known, absorbing up to 99.965% of visible light. The rights to use Vantablack for artistic purposes have been granted exclusively to the British Indian artist Anish Kapoor, which has created a great deal of public debate in artistic circles. Whether the result of fortunate accidents or years of research, discoveries of new pigments have marked the evolution of human civilisations throughout history.
