Color is one of the few disciplines that cuts across the boundaries of art, biology, physics, psychology, chemistry, geology, mineralogy, and many other fields. There is hardly an object or a substance in nature that is not colored and virtually every commercially marketed item today is either deliberately colored or de-colored.
Color production by conjugated organic compounds, coordination compounds, and semiconductors; compounds exhibiting color due to charge transfer; and a listing of representative inorganic pigments.
Artists' colors have been intertwined with chemistry from antiquity, both in the extraction of them from raw materials and their production by the 'manufacturing chemists' of their day. In our own time, not only has chemistry made possible the enormous expension of the artist's palette, but also has provided methods to study it scientifically with a view to restoration, preservation, authentication, and understanding of works of art.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
