Abstract

Two experimental data sets were accumulated for evaluating colour differences under a wide range of luminance levels using the printed colours in a spectrum tuneable viewing cabinet and self-luminous colours on a display respectively. For the surface mode experiment, pairs of samples were assessed at 9 phases ranged from 0.25 to 1128 cd/m2. For the luminous mode experiment, it was conducted in 6 phases ranged from 0.25 to 279 cd/m2. There were 140 and 42 pairs of samples judged by 20 observers using a sixcategory scales for each phase. The results were used to establish the just noticeable difference (JND) at each luminance level and showed a great agreement between two modes of colours. These were used to test the performance of 5 uniform colour spaces and colour difference equations. Also, the spaces or equations were extended to improve the fit to the present data sets.
