The open source color management solution OpenColorIO


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.

OpenColorIO is free and open source software (LICENSE), and one of several projects actively sponsored by the ASWF (Academy Software Foundation).
