✦ Synopsis
Five color-appearance transformations were light source. Several color-appearance models have been proposed that attempt to produce matches when these compared in a series of psychophysical experiments under a variety of viewing conditions. These transformations viewing conditions vary, including Fairchild and Berns's RLAB, [6][7][8] and models proposed by Hunt 9-10 and Naya-included the Hunt model, the Nayatani model, RLAB, CIELAB color space, and von Kries chromatic adapta-tani. [11][12][13] This research compared these color-appearance models to von Kries adaptation 14 and CIELAB color tion. Observers compared original printed images viewed under one set of viewing conditions to reproductions space transformations. 1 The goal was to determine which of these transformations most accurately predicted color viewed on a monitor with differing conditions. These conditions varied in white point, luminance level, background matches for a wide range of viewing condition changes. This research followed the guidelines set forth by the reflectance, and surround. Reproductions were produced using the various color-appearance models and observers International Commission on Illumination (CIE) Technical Committee 1-27, Specification of Colour Appearance decided which reproduction was the closest match to the original. RLAB was found to produce the most acceptable for Reflective Media and Self-Luminous Display Comparisons. 15 reproductions, except for changes in surround. CIELAB and von Kries adaptation also performed well. ᭧ 1997 John Printed images were used as the originals and the five color-appearance models were used to produce ''match-
