Red is the highest arc of the rainbow and corresponds to the longest wavelength of light (6500 Å) at the heat radiation limit.
The term is used in chemistry to show organic and inorganic pigments. Important examples of inorganic pigments are cadmium red, chrome and Venetian red (or red ocher), which are respectively composed by sulphoselenides cadmium, basic chromate of lead and ferric oxide. A typical organic red pigment is hemoglobin. To this category belongs also the Congo red which is usually used to dye cotton, or as a marker in analytical chemistry.
In mineralogy, the term red characterizes the colour of some serpentine rocks: the Breccia di Levanto and the Polcevera marble which are noble decorative materials. And some other limestone marbles like the Ammonitic red, the Verona red, or the Amiata red.
