William F. Powell was an internationally recognized artist and one of America's foremost colorists. A native of Huntington, West Virginia, Bill studied at the Art Student's Career School in New York; Harrow Technical College in Harrow, England; and the Louvre Free School of Art in Paris, France. He was professionally involved in fine art, commercial art, and technical illustrations for more than 45 years.

He also authored a number of art instruction books, including several popular Walter Foster titles. As a renowned master of color, Bill conducted numerous "Color Mixing and Theory" workshops in various cities throughout the U.S. His expertise in color theory also led him to author and illustrate several articles and an educational series of 11 articles entitled "Color in Perspective" for a national art magazine. Additionally, he performed as an art consultant for national space programs and for several artist's paint manufacturers. Bill's work also included the creation of background sets for films, model making, animated cartoons, and animated films for computer mockup programs.
