The correct option is c. Umbria, Italy. Pigment names are often derived from their source. For example the pigment that we call umber is named after Umbria, Italy.
A coloured substance that is entirely or almost entirely insoluble in water is called a pigment. Contrarily, dyes are usually soluble, at least initially, during their use. In general, pigments are frequently inorganic substances while dyes are frequently organic molecules. Umbers, ochres, and siennas are examples of naturally occurring inorganic pigments since they are extracted from the earth. The same names of pigments are also made synthetically. Titanium white, cobalt blue, and cadmium yellow/orange/red are more examples of manufactured inorganic pigments. Materials are given colour by adding pigments, which are chemicals. Through art, fashion, computer displays, and even health, this seemingly straightforward application has influenced how we see the world. Paints, inks, plastics, textiles, cosmetics, and food all include pigments.
