ICC.2:2017 is a revision to the next-generation colour management specification iccMAX that introduces new support for colour appearance processing. iccMAX includes a built-in colour appearance model IccCAM, together with a rich programming environment, and support for spectral data, material channel connections, BRDF and processing elements that make it possible to functionally encode any appearance model. ICC.2:2017 introduces many new capabilities, including the ability to provide environment variables which allow parameters such as image statistics or viewing conditions to be passed to the transform at run-time. ICC.2:2017 supports a wide range of colour appearance computations within the colour management workflow.
