Ladd supervised the first colorization of B&W Looney Tunes and Betty Boop cartoons in the late 1960s. He also supervised the colorization of the B&W Popeye cartoons and B&W Merrie Melodies for Turner Entertainment in 1987. These colorizations utilized a process of tracing film frames that have been blown-up to cel-size proportions. His colorizations should not be confused with the computer colorized cartoons of the 1990s.
