Final answer:
The statement regarding color in films is false as color motion pictures were in existence before the 1930s, although Technicolor and other color technologies were indeed refined and became more prevalent during that decade.
Step-by-step explanation:
The statement that color was not on the screen in any U.S. film until the 1930s when Technicolor was perfected is false. Technological advancements in color film, such as Kodachrome and Agfacolor Neu, were introduced in the mid-1930s.
However, the first color motion pictures came earlier. The Technicolor process itself had been in use in several films throughout the 1920s, though it was indeed more limited and expensive compared to the black and white films of that era. Examples of early color films include The Toll of the Sea (1922) and The Black Pirate (1926). The refinement and wider use of color technologies like Technicolor did increase during the 1930s, contributing to the popularization of color films.
