Symbolism of the Color Black Short History of Black Pigments. Carbon black was the first black. This dull black is the easiest to manufacture because it is made of charcoal. Another black is vine black, which is traditionally made by charring desiccated grape vines and stems, which produce beautiful bluish blacks. Bone black, made of burnt bones from prehistoric times, is the deepest available black.

Skin Pigmentation Melanin is made by melanocytes. Up to 8% (1 in every 5 to 10 cells) in the epidermis is a melanocyte (melano means black) make up 8% of the epidermal cells. Melanocytes make the pigment called melanin. Tyrosine is converted into dihydroxyphenylalanine (DOPA) which is then polymerised into melanin.

Paints This has a low refractive index and is used, together with titanium dioxide, to produce 'matt' paints. Other pigments include iron oxides (black, yellow and red), zinc oxide and carbon black. Powdered metals such as zinc and some metal compounds, for example zinc phosphate, have corrosion inhibiting properties.

Human biological adaptability Skin color is due primarily to the presence of a pigment called melanin , which is controlled by at least 6 genes. Both light and dark complexioned people have melanin. However, two forms are produced--pheomelanin , which is red to yellow in color, and eumelanin , which is dark brown to black. People with light complexioned skin mostly produce pheomelanin, while those with dark colored skin mostly produce eumelanin.

Black This article is about the color. For other uses, see Black (disambiguation). Black is the darkest color, the result of the absence or complete absorption of light. Like white and grey, it is an achromatic color, literally a color without hue. It is one of the four primary colors in the CMYK color model, along with cyan, yellow, and magenta, used in color printing to produce all the other colors. Black is often used to represent darkness; it is the symbolic opposite of white (or brightness). Black was one of the first colors used by artists in neolithic cave paintings. In the 14th century, it began to be worn by royalty, the clergy, judges and government officials in much of Europe.

- In the basal epithelial cells of the epidermis the carbon particles were often aggregated in the supranuclear areas (Fig. 1). After bleaching, the melanin present in the epidermis was completely decolorized. The black particles did not become decolorized, and were therefore assumed to be carbon.

Melanin Melanin /ˈmɛlənɪn/ (Greek: μέλας - melas, black, dark) is a broad term for a group of natural pigments found in most organisms (arachnids are one of the few groups in which it has not been detected).he most common type of melanin is eumelanin. There are two types of eumelanin—brown eumelanin and black eumelanin. Pheomelanin is a cysteine-containing red polymer of benzothiazine units largely responsible for red hair, among other pigmentation.

- Melanin (/ˈmɛlənɪn/ ( listen); from Greek: μέλας melas, black, dark) is a broad term for a group of natural pigments found in most organisms. Melanin is produced by the oxidation of the amino acid tyrosine, followed by polymerization. The melanin pigments are produced in a specialized group of cells known as melanocytes. There are three basic types of melanin: eumelanin, pheomelanin, and neuromelanin.
