Integrating a color management framework like OCIO (OpenColorIO) into Unreal or Unity helps establish a predictable and consistent color standard throughout the development pipeline. This includes color transforms (for converting between color spaces) and view transforms (which define how colors appear on different displays). With this system in place, designers and technical artists can ensure that tone mapping, gamma curves, and other color-related processes behave consistently across different workstations. This keeps the lighting, shadows, and overall visual presentation accurate, regardless of the device used. It also allows your teams to tailor outputs for both HDR and SDR platforms, minimizing issues like overexposure or color shifts when the final game is viewed on different screens.
Of course, your actual monitor is the first — and most important — step in this chain.
