A new experiment was carried out on a modern HP-workstation with the hope of providing a better agreement between corrected CIELUV value and subjective estimation of color differences. In the middle of a 19" screen two adjacent fields (2° or 10° in size) of different colors were shown. The left field was fixed at 5, 30, 50 and 70 CIELUV units respectively, and the color on the right field could be changed by verying its saturation and luminance. Observers were asked to adjust both colors to the same perceived color difference in relation to the background. The result shows that it was possible to achieve good agreement between predicted and perceived color differences by using a linear correction of the color coordinates u* and v*.
