Open Source Days 2025

This talk discusses how color was represented and moved through the production of DreamWorks Animation’s The Wild Robot, utilizing P3 and ACEScg Wide Color Gamuts. The increased range of color beyond sRGB, allowed visual development artists to be truer to the richer saturated colors found in the natural environments and their created color palettes. It covers how Open Source projects were critical to achieving the creative vision including MoonRay, OpenColorIO, OpenEXR, OpenImageIO, and the Academy Color Encoding System. OIIO was used to embed ICC profiles in images and OCIO applied the ACES workflow. MoonRay produced Wide Color Gamut renders with OpenEXR facilitating the storing of that image data. Transitioning the color workflow of a large studio required close collaboration between production, hardware, and software departments. Some key areas that will be discussed are modifications to artist workflows, texture precision and reworking artists’ mental model of color.
