OpenColorIO (OCIO) is an open source color management project sponsored by Sony Pictures Imageworks. Based on development started in 2003, OpenColorIO enables color transforms and image display to be handled in a consistent manner across multiple graphics applications (compositors, image playback tools, renderers, color grading, etc). Unlike other color management solutions, OCIO is geared towards motion-picture post production and is suitable for both visual effects work and animated features.

OpenColorIO has been used on dozens of feature films including Alice in Wonderland, Cloudy With A Chance Of Meatballs, Spiderman(s), Surf’s Up, and Watchmen.
