A new type of color-appearance model is presented together with its formulations. It is named In-CAM(CIELUV), which means the integrated color-appearance model using CIELUV space. Using the In-CAM(CIELUV), we can integrate its fields of applications in both colorimetric engineering and artistic color design. Various applications are introduced in colorimetric and color design fields. The In-CAM(CIELUV) connects directly colorimetric color space and perceptual Hue-Tone color order systems. In other words, the In-CAM (CIELUV) gives a colorimetric basis for Hue-Tone system. The three color attributes in the In-CAM(CIELUV) space are mutually independent. This is a very convenient feature for selecting color combinations. Some two-color combinations selected systematically in the In-CAM(CIELUV) space are shown. (C) 2008 Wiley Periodicals, Inc.
