OpenColorIO (OCIO) is a complete color management solution geared towards

motion picture production with an emphasis on visual effects and computer

animation. OCIO provides a straightforward and consistent user experience

across all supporting applications while allowing for sophisticated back-end

configuration options suitable for high-end production usage. OCIO is

compatible with the Academy Color Encoding Specification (ACES) and is

LUT-format agnostic, supporting many popular formats.



OpenColorIO is released as version 2.0 and has been in development since 2003.

OCIO represents the culmination of years of production experience earned on

such films as SpiderMan 2 (2004), Surf's Up (2007), Cloudy with a Chance of

Meatballs (2009), Alice in Wonderland (2010), and many more. OpenColorIO is

natively supported in commercial applications like Katana, Mari, Nuke, Maya,

Houdini, Silhouette FX, and

[others](https://opencolorio.org/#supported_apps).



OpenColorIO is free and open source software ([LICENSE](LICENSE)), and

one of several projects actively sponsored by the ASWF

([Academy Software Foundation](https://www.aswf.io/)).
