No. The reason is, Chromogenic microorganisms may produce intracellular pigments that are responsible for the coloration of the organisms as seen in surface colonies. Other organisms produce extracellular soluble pigments that are excreted into the medium & that also produce a color. BUT........
most organisms, however, are nonchromogenic & will appear white to gray.
