D.D. Williamson, Louisville, Ky., launched a new brand image to reflect its expanded expertise in color solutions for customers. In the new logo, “DDW” replaces “D.D. Williamson” for a concise, contemporary image, the company says. “The Color House” tagline expresses a place where creativity blends with advanced technical capability to bring color ideas to life, it adds. The company also announced its annual Natural Coloring Competition for Students to encourage learning about naturally derived coloring. Two winners will receive a trip to the 2012 IFT Annual Meeting in Las Vegas and display their project poster in the D.D. Williamson booth at the IFT Food Expo. Abstract submissions are due Nov. 14 and winners will be announced by April 15.
