Kodak claims that Kodacolor was "the world's first true color negative film".
The name "Kodacolor" was originally used for a very different lenticular color home movie system, introduced in 1928 and retired after Kodachrome film made it obsolete in 1935.
When introduced, Kodacolor was sold with the cost of processing the film included, but prints were ordered separately.
After Kodak lost its anti-trust case in 1954, starting in 1955 processing was no longer included in the price of Kodacolor.
Kodacolor-X is a color negative film that was manufactured by Eastman Kodak between 1963 and 1974.
Surviving exposed (but unprocessed) Kodacolor-X and C-22 films can still yield color images, although this requires highly specialised development techniques.
Kodacolor II was the first of a new generation of Kodak color negative films using the C-41 process.
It was designed as a major improvement to meet the needs of the small 13×17 mm negatives used in 110 film for the Kodak Pocket Instamatic cameras.
The Kodacolor VR films were also Kodak's first to use developer-inhibitor-releaser, which improved edge effects for higher sharpness.
