Topping sugars and icings can be given a natural blue color — or black, green, orange, pink, purple, red or yellow — with colorings produced through a partnership between D.D. Williamson & Co. and colorMaker. The standard colors are application specific, while custom blends can be tailored to even more exacting product requirements.
