**Abstract**

The prediction performance of three color-difference formulas (CIE76 - Euclidean distance in CIELAB, CIE94 and CIEDE2000) was evaluated on an LCD (Liquid Cristal Display) typically used in soft-proofing applications. For this purpose we conducted an LCD-based visual experiment to analyze perceived color differences around five color centers recommended by the CIE and created a new color-difference dataset. The performance of the color difference formulas to predict these perceived differences was evaluated by the STRESS index, which allows also a statistical analysis whether one formula is significantly better than another. It was found that the CIE94 and CIEDE2000 formulas perform significantly better than CIE76. For default parametric variables (kL= kC = kH =1) the CIEDE2000 formula performs significantly better than the CIE94 formula. If the parametric variables are optimized both formulas perform almost equally. We analyzed the over- and under-fitting behavior of the formulas and could verify the results of other investigations that predicted color differences on typical LCDs are perceived smaller than similar differences on hard-copies.**Keywords: **STRESS; color difference; F-test; LCD**Contact:**
