Reference Input/Output Medium Metric RGB Color Encoding (RIMM/ROMM RGB)

A new color encoding specification known as Reference Output Medium Metric RGB (ROMM RGB) is defined. This color encoding is intended to be used for storing, interchanging and manipulating images that exist in a rendered image state without imposing the gamut limitations normally associated with device-specific color spaces. ROMM RGB was designed to provide a large enough color gamut to encompass most common output devices, while simultaneously satisfying a number of other important criteria. It is defined in a way that is tightly linked to the ICC profile connection space (PCS) and is suitable for use as an Adobe Photoshop™ working color space. A companion color encoding specification, known as Reference Input Medium Metric RGB (RIMM RGB), is also defined. This encoding can be used to represent images in an unrendered scene image state.
