The colors of the rainbow have just gotten brighter. With the acquisition of the Dinesen Trading Company in Port Washington, Wis., D.D. Williamson has broadened the range of colors in its portfolio. The Wisconsin facility will be the central source for its expanded natural colors operation. The new colors—including annatto, paprika and carmine—will join the elderberry and chokecherry colors (from July's acquisition of Artemis International) in D.D. Williamson's colorMaker™ natural color line. D.D. Williamson, Campbell Barnum, 502-895-2438,
