Even though we continue to use age old processes to prepare pigments and convert them into paint, modern pigments are synthesized in laboratories. Birds and mammals possess these pigment cells, which are found mainly in the epidermis, though they occur elsewhere—e.g., in the matrix of the hair. In some cases, health problems can develop if too much pigment collects in the body or if too little is made. So, although hemoglobin, chlorophyll, melanin, and bilirubin (as examples) don't fit the narrow definition of pigment in science, they are biological pigments.
