In recent years PY74 has become the standard mid yellow arylide color. The names azo and arylide are often used for a wide range of closely related lake pigments. They form the backbone of the modern high performance organic pigment industry. Without these colors then cars and plastics would be available in only a limited number of colors and artists would have far fewer choices than we do now. Yellow Mid Azo is a slightly greener shade than Cadmium Yellow Medium but it is fairly close to the Cadmium color. So why have two pigments so nearly the same? There are three reasons – money, transparency and clarity of color.
