Also Known As: Colorized. A film alteration process where an operator digitally alters a black and white image to include color. It is a controversial practise because many filmmakers and viewers believe it fundamentally alters an artistic creation. Early attempts at colorization in the 1980's were relatively crude in their shading range. Examples of this kind of alteration are versions of Casablanca and It's a Wonderful Life. Citizen Kane is notable in that Orson Welles was able to legally prevent its alteration.
