Film colorization is any process that involves adding color to black and white, sepia or monochrome moving-picture images. The earliest examples date back to the early 20th century, but it has become easier and more common since the development of digital image processing.
It has been done with different effects for various reasons, including as a special effect or as a form of restoration for color films. The process has also garnered controversy because of its use to reissue black and white films and television shows in color. Some have claimed that this use of the process is a form of "cultural vandalism".
